May act as a positive modulator of hmr-1 function during epidermal morphogenesis (PubMed:12847081). Required for proper localization of other junctional components, such as pac-1 (PubMed:25938815). Associated with the catenin-cadherin complex consisting of hmr-1, hmp-1 and hmp-2 (PubMed:25938815). Interacts with hmr-1 (PubMed:12847081, PubMed:25938815). Interacts with picc-1 (PubMed:25938815). Epidermal cells. Expressed in the early epidermis. Embryos are viable, but display a partial loss of junctional component, pac-1, from adherens junctions. Belongs to the beta-catenin family.
