Profilins are small actin-binding proteins found in eukaryotes and certain
viruses that are involved in cell development, cytokinesis, membrane
trafficking, and cell motility. Originally identified as an actin
sequestering/binding protein, profilin has been involved in actin polymerization
dynamics. It catalyzes the exchange of ADP/ATP in actin and increases the rate
of polymerization. Profilins a... hiện toàn bộ
