Predicted to enable several functions, including beta-catenin binding activity; gamma-catenin binding activity; and protein tyrosine phosphatase activity. Involved in T cell differentiation; cell adhesion; and neuron projection development. Predicted to be located in several cellular components, including leading edge membrane; neuronal cell body; and photoreceptor outer segment. Orthologous to human PTPRK (protein tyrosine phosphatase receptor type K). [provided by Alliance of Genome Resources, Apr 2022]
