Phactr1, Phosphatase and actin regulator 1
Also Known as
Binds actin monomers (G actin) and plays a role in the reorganization of the actin cytoskeleton and in formation of actin stress fibers. Plays a role in the formation of tubules by endothelial cells. Regulates PPP1CA activity. Required for normal cell survival (By similarity). Plays a role in cell motility. Interacts (via RPEL repeats) with ACTA1 and PPP1CA; ACTA1 and PPP1CA compete for the same binding site.
