Protein
Twinfilin-2
Gene
TWF2
Organism
Pongo abelii (Sumatran orangutan) (Pongo pygmaeus abelii)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

Actin-binding protein involved in motile and morphological processes. Inhibits actin polymerization, likely by sequestering G-actin. By capping the barbed ends of filaments, it also regulates motility. Seems to play an important role in clathrin-mediated endocytosis and distribution of endocytic organelles. May play a role in regulating the mature length of the middle and short rows of stereocilia By similarity.

Interactioni

Subunit structurei

Interacts with G-actin; ADP-actin form and capping protein (CP). May also be able to interact with TWF1 and phosphoinositides, PI(4,5)P2. When bound to PI(4,5)P2, it is down-regulated. Interacts with MYO7A By similarity.
