Function
Plays an important role in the organization of the cytoskeleton by regulating actin polymerization in two ways. Firstly, by binding to and sequestering actin monomers (G actin) inhibits actin polymerization. Secondly, by binding directly filamentous actin (F actin) promotes actin polymerization. Regulates the formation of cortical actin in oocytes conferring them enough rigidity to sustain the contractions during ovulation.
