The present invention relates to the production of gene sequences encoding chimerical membrane glycosyltransferases presenting an optimized glycosylat ion activity in cells transformed with said sequences, said gene sequences corresponding to the fusion : of a first nucleic acid coding for a C-terminal minimal fragment of the catalytic domain (CD) of the native full length glycosyltransferase, to a second nucleic acid coding for a transmembrane peptide comprising in its N-terminal region a cytoplasmic tail (CT) region located upstream fro m a transmembrane domain (TMD), itself located upstream of a stem region (SR), provided that at least one of these CT, TMD, SR peptides being different from the primary structure of the naturally occurring peptide counterparts present in the native glycosyltransferase from which is derived the CD fragment with optimal glycosyltransferase activity as defined above. The invention also relates to the use of said gene sequences in the frame of the preparation of recombinant proteins of interest by cells transformed with said sequences and sequences encoding said recombinant proteins.

La présente invention concerne la production de séquences géniques codant des glycosyltransférases membranaires chimériques qui présentent une activité de glycosylation optimisée dans des cellules transformées avec lesdites séquences, lesdites séquences géniques correspondant à la fusion : d'un premier acide nucléique codant un fragment C-terminal minimal du domaine catalytique (CD) de la glycosyltransférase pleine longueur native avec un second acide nucléique codant un peptide transmembranaire qui comporte dans sa région N-terminale une région de queue cytoplasmique (CT) située en amont d'un domaine transmembranaire (TMD), lui-même situé en amont d'une région souche (SR), à la condition qu'au moins un desdits peptides CT, TMD, SR soit différent de la structure primaire des homologues peptidiques naturels présents dans la glycosyltransférase native de laquelle est dérivé le fragment CD présentant l'activité glycosyltransférase optimale, telle qu'elle a été définie précédemment. L'invention concerne également l'utilisation desdites séquences géniques dans le cadre de la préparation de protéines recombinantes d'intérêt au moyen de cellules transformées avec lesdites séquences, de même qu'elle concerne les séquences codant lesdites protéines recombinantes.
