May be involved in formation of stretch-resistant cell-cell adhesion complexes.
Subcellular locations: Cytoplasm, Cytoskeleton, Cell junction, Desmosome
Localizes to intercalated disks of cardiomyocytes and in peritubular myoid cells of testis, and colocalizes with CTNNA1 and CTNNA2. Colocalizes with PKP2 at intercalated disks in the heart (By similarity).
Predominantly expressed in heart and testis. Expressed at lower levels in brain, kidney, liver and skeletal muscle.
