Predicted to be involved in cell adhesion. Predicted to act upstream of or within calcium-dependent cell-cell adhesion via plasma membrane cell adhesion molecules and homophilic cell adhesion via plasma membrane adhesion molecules. Predicted to be located in cell junction; nucleolus; and nucleoplasm. Predicted to be integral component of plasma membrane. Is expressed in several structures, including central nervous system; genitourinary system; gut; heart; and sensory organ. Orthologous to human PCDH1 (protocadherin 1).
