Ptprk Gene Summary [Rat]
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, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Ptprk often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
