Function

May be involved in formation of stretch-resistant cell-cell adhesion complexes.
Tissue specificity

Predominantly expressed in heart and testis. Expressed at lower levels in brain, kidney, liver and skeletal muscle.
Sequence similarities

Belongs to the vinculin/alpha-catenin family.
Cellular localization

Cytoplasm > cytoskeleton. Localizes to intercalated disks of cardiomyocytes and in peritubular myoid cells of testis, and colocalizes with CTNNA1 and CTNNA2.
