unc-95 encodes a LIM domain-containing protein related to Drosophila and vertebrate paxillins; UNC-95 is required for locomotion and organization of thick and thin filaments in body wall muscle; by homology, UNC-95 may function as an anchor protein that links signaling and cytoskeletal proteins at focal adhesions; in vitro, UNC-95 interacts with RNF-5, a RING finger protein that may function as an E3 ligase to regulate UNC-95 levels via ubiquitin-mediated degradation; UNC-95 is expressed in body-wall and vulval muscles, and co-localizes with RNF-5 to muscle dense bodies (focal adhesion-like attachment sites).
