| 摘要 |
The invention relates to Optineurin-derived polypeptide(s) consisting of a polypeptidic sequence disclosed in SEQ ID no2, which represents the portion of the wild-type human Optineurin protein sequence from its amino-acid residue 131 to its amino-acid residue 297, or having a polypeptidic sequence encompassing the polypeptidic sequence disclosed in SEQ ID no2, or having a polypeptidic sequence derived from the polypeptidic sequence disclosed in SEQ ID no2 to the exclusion of the wild-type Optineurin protein. The polypeptide(s) of the invention retain one, any combination of two, or three of the following functional properties: the capacity to bind Rab8 protein, when the latter are associated with the Golgi apparatus of a cell, the capacity to bind MYPT1 protein, when said protein is engaged in a Myosin-Phosphatase (MP) complex, the capacity to be phosphorylated by Plk1. The invention also relates to nucleic acid molecule(s) encoding such polypeptide(s), vector(s) and method(s) of production thereof, alteration(s). |
