PTPN1
nonreceptor type1 gene, which encodes
PTP1B the
prototypic member of the PTP family is responsible for
negatively regulating
insulin by dephosphorylating the
phosphotyrosine (ptyr)
residues* of the insulin receptor (
INSR) kinase activation segment
IRK (
kinase domain of the insulin receptor) mainly by its association with
IR localized to the
plasma membrane in a
Grb2 fashion, or by inhibiting insulin signaling locus:
20q13.1-q13.2 (
EC 3.1.3.48), [
§§] as well as
JAK2 and TYK2 kinases.
Leptin as well as
insulin, induced the expression of
PTP1B and T cell
protein tyrosine phosphatase (
TC-PTP) a closely related phosphatase.
TYK2 and
JAK2 are substrates, PTP1B expression augments
STAM2 an
RTK, phosphorylation downstream of
JAK kinases. PTP-1B encoded by the PTPN1 gene and
T-cell–
PTP localizes to the endoplasmic
reticulum␠ oriented towards the cytoplasm (located on the
cytosolic side of the endoplasmic reticulum post-translational

N-cadherin binds PTP1B to

dephosphorylation and deactivation of insulin
