Definitions
- the invention relates to polypeptides allowing the direct secretion of proteins produced in eukaryotic cells.
- a cleavable N-terminal signal peptide is added to the protein which it is desired to secrete, by proceeding to the fusion of a sequence coding for said signal peptide with the sequence coding for the recombinant protein.
- This signal peptide allows the translocation of the polypeptide through the membrane of the endoplasmic reticulum, through which it will be transported, in the vesicles of the Golgi apparatus, to the plasma membrane.
- this approach does not always lead to the expected result [JARVIS et al., J. Biol. Chem. n ° 268, p. 16754-16762, (1993)].
- receptors are made up of an extracellular N-terminal region, a transmembrane region and an intra-C-terminal region - cytoplasmic (for review, see for example [DUSANTER-FOURT et al., Médecine / Sciences Syntician, 10, p. 825-835, (1994)]).
- the prolactin receptor exists in two forms: a short form, consisting of 291 amino acids, and a long form, consisting of 591 amino acids in rats, 592 amino acids in rabbits, and 598 amino acids in humans) .
- the growth hormone receptor consists of 620 amino acids (in humans and rabbits) and has many regions homologous with the long form of the prolactin receptor [KELLY et al. , in Recent Progress in Hormon Research, 48, P. 123 (Académie Press Ed. (1993); KELLY and DJIANE, US Patent 4,992,398]: in particular, we find in the intra-cytoplasmic region 4 conserved regions.
- receptors of the same family erythropoietin receptor, growth factor receptors, interleukin receptors 2, 3, 4, 5, 6, 7, and 9, GM-CSF receptor, G-CSF, receptor 1 ⁇ interferon, etc ].
- Other receptors of the same family erythropoietin receptor, growth factor receptors, interleukin receptors 2, 3, 4, 5, 6, 7, and 9, GM-CSF receptor, G-CSF, receptor 1 ⁇ interferon, etc ].
- functional chimeric receptors comprising the extra-cytoplasmic domain of a first receptor, and the domain intracytoplasmic of a second receptor, separated by a transmembrane domain belonging either to the first or to the second receptor [MOORE et al.
- the intra-cytoplasmic region of the prolactin receptor is not only capable of being exported into the culture medium when it is expressed alone, but could also allow the export of a protein.
- transient protein fused at its C-terminal end.
- the Inventors have also highlighted the minimum region responsible for this property.
- the inventors have also observed that the intra-cytoplasmic region of the growth hormone (GH) receptor, expressed in a baculovirus / insect cell system, is excreted in the culture medium in a manner analogous to the intra- prolactin receptor cytoplasmic.
- the inventors have thus identified, in particular, a polypeptide of 372 amino acids, coded by the fragment of the sequence coding for the growth hormone receptor comprised between the Ncol site and the stop codon of said sequence, and a polypeptide of 329 amino acids, coded by the fragment of the sequence coding for the growth hormone receptor between the ClaI site and the stop codon of said sequence.
- the demonstration by the inventors of these characteristics of prolactin and growth hormone receptors makes it possible to envisage the use of the intra-cytoplasmic domains of cytokine receptors, and more particularly of the intra-cytoplasmic domains of receptors for prolactin and growth hormone as transporters to allow the export, from a host cell, of proteins of interest whose localization is usually cytoplasmic or nuclear.
- the subject of the present invention is the use of a protein whose polypeptide sequence is chosen from the group consisting of:
- GH growth hormone
- GH growth hormone receptor
- a chimeric fusion protein comprising the protein of interest which it is desired to export, produced at its N-terminal end by the intra region, is produced by a system of expression in eukaryotic cells.
- -cytoplasmic of the prolactin receptor or by the intra-cytoplasmic region of the growth hormone receptor, or by a fragment, as defined above, of one or other of these regions.
- the chimeric proteins according to the invention do not include a transmembrane domain.
- the two regions of the chimeric protein can be directly fused, or separated by an oligopeptide providing a specific site for cleavage by a protease (for example a site for cleavage for an enterokinase (EC 3.4.21.9), or for factor Xa (EC 3.4.21.6) or any other specific protease) .
- a chimeric protein according to the invention can be obtained by constructing, by conventional techniques of molecular biology, a recombinant gene coding for this protein.
- a recombinant gene comprises a DNA sequence coding for the protein of interest which it is desired to express, fused at its 5 ′ end with a sequence coding for the intra-cytoplasmic domain of the prolactin receptor or the l receptor.
- growth hormone or for a fragment, as defined above, of one or other of these domains; advantageously, these two sequences are separated by a sequence coding for an oligopeptide carrying a specific site for cleavage by a protease.
- the implementation of the present invention allows the recovery of the recombinant proteins from the culture medium, which facilitates their purification.
- the present invention also encompasses vectors carrying at least one recombinant gene as defined above, and in particular expression vectors in which said recombinant gene is placed under the control of expression regulation sequences active in the host cell. chosen.
- said expression vectors can be constituted by modified baculoviruses in which at at least one recombinant gene according to the invention is placed under transcriptional control of a baculovirus promoter.
- GENERAL EXPERIMENTAL PROTOCOLS A - Cell and virus cultures Spodoptera frugiperda Sf9 cells are maintained at 28 ° C in TC100 medium supplemented with 5% fetal calf serum.
- the baculovirus AcMNPV wild virus
- the recombinant baculoviruses are propagated in these Sf9 cells.
- the cells (4 ⁇ 10 6 per 25 cm 2 bottle) are inoculated using a viral suspension at a multiplicity of infections of 10 PFU per cell. After one hour of adsorption at room temperature, the viral inoculum is removed and fresh culture medium is added.
- Recombinant viruses are obtained after co-transfection of Sf9 cells with viral DNA, and DNA of the transfer vector, by lipofection (DOTAP, Boerhinger Mannheim, Germany) [FELGNER and RINGOLD, Nature no. 337, p. 387-388, (1989)].
- DOTAP Boerhinger Mannheim, Germany
- FELGNER and RINGOLD Nature no. 337, p. 387-388, (1989)].
- the screening and the purification of the recombinant viruses are carried out according to the current procedures described for example by SUMMERS and SMITH [Texas Agric. Exp. St. Bull., N ° 1555, p. 1-56,
- the long form of the rabbit prolactin receptor consists of an N-terminal extracellular domain of 210 amino acids, a transmembrane region of 24 amino acids and an intra-cytoplasmic C-terminal region of 358 amino acids.
- Figure 1 Several cleavage sites by restriction enzymes are present on the gene coding for the rabbit prolactin receptor [EDERY et al. , Proc. Natl. Acad. Sci. USA, No. 86, 2112-2116 (1989)].
- the 5kb cDNA sequence which codes for the rabbit prolactin receptor was cloned from the plasmid pECE-PRL-R 2 4 described by EDERY et al. (1989, Publication cited above) in a plasmid pUC18, to give the plasmid pUC18 L2 PRL-R [CAHOREAU et al., Biochemistry, n ° 74, p. 1053-1065, (1992)].
- the transfer plasmids for baculoviruses of the pGmAc family are prepared from the EcoRI-I fragment of the baculovirus of the Autographa californica nuclear polyhedrosis (AcMNPV) which contains the gene and the polyhedrin promoter, by inserting said fragment in the bacterial plasmid pUC8.
- AcMNPV Autographa californica nuclear polyhedrosis
- the coding sequence located between nucleotides + 24 and + 522 (relative to the A (+ 1) of ATG) of the polyhedrin gene was deleted and replaced by a Striai linker, which allows the insertion of a heterologous sequence in phase behind the ATG of the polyhedrin.
- the recombinant protein is thus produced in the form of a fusion protein with the first 7 amino acids of polyhedrin.
- this plasmid has a KpnI restriction site located 109 nucleotides downstream from the SmaI site.
- the plasmids pGmAc31I 1 , pGmAc31I 2 and the recombinant baculoviruses expressing these plasmids are obtained as described in the publication by CAHOREAU et al. [CAHOREAU et al., Biochemistry, n ° 74, p. 1053-1065,
- BstEII-Kpnl of 1151 bp comprising the entire sequence coding for the intra-cytoplasmic part of the prolactin receptor, between the SmaI site and the site
- Kpn1 of pGmAc31 and comprises a sequence coding for 353 C-terminal amino acids of the prolactin receptor.
- pGmAc31l2 results from the insertion of a Smal-Kpnl fragment of 998 bp between the Smal site and the Kpnl site of pGmAc31, and comprises a sequence coding for 302 amino acids
- This plasmid comprises the BstEII-Bsu36I subfragment of fragment I ⁇ . This subfragment codes for 114 N-terminal amino acids of I ] _. - pGmAcl68l4: The plasmid pGmAc31l2 was cleaved using
- pGmAc31I 1 was digested with Xbal and Bsu36I; an XbaI-Bsu36I fragment has been deleted; the ends on either side of this fragment were made blunt using the KLENOW polymerase, and ligated with a BamHI linker (10 mer).
- the plasmid obtained comprises a sub-fragment which codes for 52 N-terminal amino acids of I ⁇ ,, fused to a sub-fragment which codes for 239 C-terminal amino acids of I ⁇ .
- the inserts I ⁇ _, I 2 , I3, I4, I5 located with respect to the sequence coding for the intracytoplasmic domain of prolactin, are represented in FIG. 1 by solid white rectangles.
- the polyhedrin promoter is shown in solid black; the beginning of the polyhedrin coding sequence is represented by black dots on a white background.
- ACP ⁇ 1I3, ACP ⁇ 1I4 and ACPI1I5 were obtained by homologous recombination between pGmAc3ll3, PG111ACI68I4, and pGmAc31l5, respectively, and the total DNA of wild type AcMNPV.
- a recombinant baculovirus expressing the protein I 2 was used as a positive control.
- Cyclin A or cyclin B have been used as transient proteins. Cyclin A and cyclin B have already been expressed in the baculovirus / insect cell system. Under these conditions, cyclin A is present in the nucleus of infected cells [ZINDY F., "Study of the functions and expression of normal human cyclin A and its modified form by integration of the DNA of the virus of hepatitis B ", Thesis, University
- the transfer vector pGmAc31I 2 was modified by mutation of the stop codon (TGA) of the intra-cytoplasmic domain of the prolactin receptor, so that a KpnI site replaces it.
- the Kpnl-Kpnl fragment is then deleted by digestion using the restriction enzyme Kpnl. then the vector is religated.
- the two cDNAs coding for cyclin A and cyclin B respectively were inserted into the unique remaining Kpnl site: the cyclin B gene was cut by HindIII, repaired by the enzyme of KLENOW and Smal, then inserted into the Kpnl site repaired by the KLENOW enzyme, from the transfer vector.
- the different stages of this construction are illustrated in FIG. 2.
- the complete sequence of the gene coding for cyclin B was inserted at the BglII site repaired by the enzyme of KLENOW, from the transfer vector pGmAc31l 3 .
- cyclin A the ATG of the gene has been replaced so that a Kpnl site is obtained, and a Kpnl-Kpnl fragment containing the entire cyclin A gene has been directly inserted at the Kpnl site of the transfer vector.
- the CycB gene was thus inserted into the transfer vectors pGmAc31I 2 and pGmAc31l3, and the CycA gene was inserted into pGmAc31I 2 .
- the recombinant viruses respectively named AcPhI 2 -CycB, AcPhl 3 -CycB, and AcPhI 2 -CycA were obtained by homologous recombination between these transfer vectors, and the total DNA of wild-type AcMNPV.
- Baculoviruses expressing only the sequences coding for cyclin A and cyclin B not fused with the intra-cytoplasmic domain of the prolactin receptor, were also constructed as a control.
- Spodoptera frugiperda cells were infected with each of the recombinant viruses for 48 hours, and the proteins from cell extracts and culture supernatants were characterized by immunoelectrotransfer, using a polyclonal serum anti-prolactin receptor.
- the chimeric proteins I 2 -CycB and I 2 -CycA are present both in cell lysates and in cell culture media. Each of the proteins fused to I 2 is therefore secreted efficiently.
- the chimeric protein I 3 -CycB accumulates in the cytoplasm, which indicates that the deletion of the C-terminal portion of the domain I 2 substantially reduces the efficiency of secretion.
- Immunodetection using an anti-ubiquitin antiserum shows that I 2 CycB and I 2 CycA are ubiquitinylated, while CycA, CycB, and l 3 CycB are not. It is therefore possible that ubiquitin residues play a role in the secretion process.
