Patent

CA 2459013

It is intended to provide proteins having effects of controlling cell migration and cell death of nerve cells, etc. and DNAs encoding these proteins. In particular, it is intended to provide a method of controlling cell migration and/or cell death and a method of screening a substance capable of promoting or suppressing the effects of controlling cell migration and/or cell death with the use of proteins controlling the mobility and cell death of nerve cells, etc. by interacting an actin-binding protein and thus promoting the decomposition of the actin-binding protein and DNAs encoding these proteins. c-DNAs of S-FILIP, L-FILIP and h-FILIP, each interacting with an actin-binding protein Filamin 1 and thus promoting the decomposition of Filamin 1, thereby negatively controlling cell migration and participating in cell death, are isolated and the full base sequences and amino acid sequences thereof are determined.

La présente invention concerne des protéines pouvant commander la migration cellulaire et la mort cellulaire de cellules nerveuses, etc. La présente invention concerne également des ADN codant ces protéines. Cette invention concerne notamment un procédé pour commander la migration cellulaire et/ou la mort cellulaire et un procédé pour cribler une substance capable de favoriser ou de supprimer les effets de commande de la migration cellulaire et/ou de la mort cellulaire, à l'aide de protéines commandant la mobilité et la mort cellulaire de cellules nerveuses, etc., par interaction avec une protéine de liaison à l'actine, favorisant ainsi la décomposition de cette protéine de liaison à l'actine et des ADN la codant. Des ADN complémentaires de S-FILIP, L-FILIP et h-FILIP, interagissant chacun avec une protéine de liaison à l'actine Filamine 1 et favorisant ainsi la décomposition de Filamine 1, ce qui induit une commande négative de la migration cellulaire et une participation à la mort cellulaire, sont isolés et les séquences de base complètes et des séquences d'acides aminés de ceux-ci sont déterminées.
