Enables several functions, including alpha-catenin binding activity; beta-catenin binding activity; and delta-catenin binding activity. Acts upstream of or within protein dephosphorylation. Predicted to be located in cell surface and plasma membrane. Predicted to be integral component of plasma membrane. Is expressed in several structures, including alimentary system; nervous system; respiratory system; sensory organ; and skeleton. Human ortholog(s) of this gene implicated in colorectal cancer and esophagus squamous cell carcinoma. Orthologous to human PTPRT (protein tyrosine phosphatase receptor type T).
