 '''Beta-parvin''' (BPAR) is an actin-binding protein which contains calponin homo;ogy (CH) domains which bind actin filaments.  BPAR which has a role in cytoskeleton organization and cell adhesion.   BPAR inhibits integrin-linked kinase signaling and is downregulated in breast tumors<ref>PMID: 15467740</ref>
