Function[ACTB_BOVIN] Actins are highly conserved proteins that are involved in various types of cell motility and are ubiquitously expressed in all eukaryotic cells. [PROF1_BOVIN] Binds to actin and affects the structure of the cytoskeleton. At high concentrations, profilin prevents the polymerization of actin, whereas it enhances it at low concentrations. By binding to PIP2, it inhibits the formation of IP3 and DG. Inhibits androgen receptor (AR) and HTT aggregation and binding of G-actin is essential for its inhibition of AR (By similarity).

Publication Abstract from PubMedThe three-dimensional structure of bovine profilin-beta-actin has been solved to 2.55 A resolution by X-ray crystallography. There are several significant local changes in the structure of beta-actin compared with alpha-actin as well as an overall 5 degrees rotation between its two major domains. Actin molecules in the crystal are organized into ribbons through intermolecular contacts like those found in oligomeric protein assemblies. Profilin forms two extensive contacts with the actin ribbon, one of which appears to correspond to the solution contact in vitro.
