[[http://www.uniprot.org/uniprot/ACTS_MOUSE ACTS_MOUSE]] Actins are highly conserved proteins that are involved in various types of cell motility and are ubiquitously expressed in all eukaryotic cells. [[http://www.uniprot.org/uniprot/PHAR1_MOUSE PHAR1_MOUSE]] 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.<ref>PMID:22976292</ref> <ref>PMID:23041370</ref>
