Target Information
T-cell protein tyrosine phosphatase (TC-PTP), also known as PTPT and PTPN2, is an enzyme that removes phosphate groups covalently attached to tyrosine residues in proteins.
This enzyme has two C-terminal splice variants with distinct subcellular localizations:
- The 45 kDa isoform is nuclear in resting cells and redistributes to the cytosol upon stimulation with growth factors or stress.
- The 48 kDa isoform is localized in the endoplasmic reticulum and appears to have different physiological substrates.
TC-PTP is abundant in hematopoietic cells. Knockout mice lacking TC-PTP die 3–5 weeks after birth due to erythropoietic and lymphopoietic deficits, indicating its essential role in bone marrow maturation. TC-PTP dephosphorylates a wide range of phosphoproteins, including p52 Shc and receptors for EGF, insulin, and growth hormone.
