View in BioMuta


PTPRC is a member of the protein tyrosine phosphatase (PTP) family. Members of the PTP family are signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitosis, and oncogenic transformation. PTPRC is required for T-cell activation through the antigen receptor. PTPRC contains an extracellular domain, a single transmembrane segment and two tandem intracytoplasmic catalytic domains, and is classified as a receptor type PTP.
