Protein Structure

UniProt Annotation

Function

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. {ECO:0000250, ECO:0000269PubMed:22976292, ECO:0000269PubMed:23041370}.

Subcellular Localization

Cytoplasm. Cell junction, synapse {ECO:0000250}. Nucleus. Note=Enriched at synapses (By similarity). Cytoplasmic in resting cells, and is imported into the nucleus upon serum stimulation. Interaction with actin prevents nuclear import. {ECO:0000250}.
