Enables cadherin binding activity involved in cell-cell adhesion. Involved in cell-cell adhesion via plasma-membrane adhesion molecules; negative regulation of apoptotic process; and positive regulation of cell motility. Located in bicellular tight junction; cell surface; and lateral plasma membrane. Is integral component of membrane. Biomarker of middle cerebral artery infarction. Human ortholog(s) of this gene implicated in congenital diarrhea 5 with tufting enteropathy and hereditary nonpolyposis colorectal cancer type 8. Orthologous to human EPCAM (epithelial cell adhesion molecule). [provided by Alliance of Genome Resources, Apr 2022]
