Protein tyrosine phosphatase non receptor type 2, PTN2, Ptpn2, PTPT, T cell protein tyrosine phosphatase, TC PTP, TCELLPTP, TCPTP, Tyrosine protein phosphatase non receptor type 2.
Tyrosine-protein phosphatase which acts as a regulator of endoplasmic reticulum unfolded protein response. Mediates dephosphorylation of EIF2AK3/PERK, inactivating the protein kinase activity of EIF2AK3/PERK. May play an important role in CKII- and p60c-src-induced signal transduction cascades.
