Function

Non-receptor type tyrosine-specific phosphatase that dephosphorylates receptor protein tyrosine kinases including INSR, EGFR, CSF1R, PDGFR. Also dephosphorylates non-receptor protein tyrosine kinases like JAK1, JAK2, JAK3, Src family kinases, STAT1, STAT3 and STAT6 either in the nucleus or the cytoplasm. Negatively regulates numerous signaling pathways and biological processes like hematopoiesis, inflammatory response, cell proliferation and differentiation, and glucose homeostasis. Plays a multifaceted and important role in the development of the immune system. Functions in T-cell receptor signaling through dephosphorylation of FYN and LCK to control T-cells differentiation and activation. Dephosphorylates CSF1R, negatively regulating its downstream signaling and macrophage differentiation. Negatively regulates cytokine (IL2/interleukin-2 and interferon)-mediated signaling through dephosphorylation of the cytoplasmic kinases JAK1, JAK3 and their substrate STAT1, that propagate signaling downstream of the cytokine receptors. Also regulates the IL6/interleukin-6 and IL4/interleukin-4 cytokine signaling through dephosphorylation of STAT3 and STAT6 respectively. In addition to the immune system, it is involved in anchorage-dependent, negative regulation of EGF-stimulated cell growth. Activated by the integrin ITGA1/ITGB1, it dephosphorylates EGFR and negatively regulates EGF signaling. Dephosphorylates PDGFRB and negatively regulates platelet-derived growth factor receptor-beta signaling pathway and therefore cell proliferation. Negatively regulates tumor necrosis factor-mediated signaling downstream via MAPK through SRC dephosphorylation. May also regulate the hepatocyte growth factor receptor signaling pathway through dephosphorylation of the hepatocyte growth factor receptor MET. Also plays an important role in glucose homeostasis. For instance, negatively regulates the insulin receptor signaling pathway through the dephosphorylation of INSR and control gluconeogenesis and liver glucose production through negative regulation of the IL6 signaling pathways. May also bind DNA.

Activity summary

TCPTP or T-cell protein tyrosine phosphatase is an enzyme that functions mechanically by removing phosphate groups from tyrosine residues on its substrate proteins. This process helps regulate various signaling pathways within cells. Also known as PTPN2 TCPTP is a protein with a mass of approximately 48 kDa. Its expression occurs in many tissues with notable levels in hematopoietic cells and within the endoplasmic reticulum.

Biological function summary

TCPTP plays a role in the control of cell growth differentiation and immune response. It functions independently not as part of a larger complex. This enzyme acts as a negative regulator of signaling pathways by dephosphorylating proteins that drive these cellular processes. Its activity ensures a balance in cellular signaling preventing overactivation which could lead to uncontrolled cell proliferation or inappropriate immune responses.

Pathways

TCPTP holds significant function in the JAK-STAT and insulin signaling pathways. Within the JAK-STAT pathway TCPTP dephosphorylates members such as JAK1 and JAK3 helping modulate cytokine responses and immune regulation. In the insulin signaling pathway it influences the dephosphorylation of the insulin receptor thereby impacting insulin sensitivity. Such interactions demonstrate its involvement in key cellular processes necessary for immune function and metabolic regulation.

Associated diseases and disorders

TCPTP has associations with autoimmune diseases such as Type 1 Diabetes and Crohn’s Disease. Reduced activity or altered expression of TCPTP has been observed in these conditions suggesting its regulatory role in immune tolerance. Furthermore its connection with proteins like the cytokine IL-6 in autoimmune responses implicates TCPTP in the disease mechanisms where disrupted signaling can contribute to chronic inflammation and immune system dysfunction.
