Component of an integrin containing attachment complex, which is required for muscle development and maintenance (PubMed:22253611). Probably function in adherens junction (PubMed:12808046). Affects the structural integrity of the integrin containing muscle adherens junctions and contributes to the mechanosensory functions of touch neurons (PubMed:12808046). Interacts with unc-98 (PubMed:12808046). Component of an integrin containing attachment complex, composed of at least pat-2, pat-3, pat-4, pat-6, unc-52, unc-97 and unc-112 (PubMed:22253611). Restricted to tissue types that attach to the hypodermis, specifically body wall muscles, vulval muscles, and mechanosensory neurons. RNAi-mediated knockdown results in impaired mobility, mitochondrial fragmentation and disrupted integrin attachment complexes in muscle. This leads to degradation of muscle proteins in the cytosol, myofibrillar defects and disruption of sarcomere organization.
