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

plasma membrane

^ as well as
JAK2
and TYK2 kinases.
Leptin as

insulin, induced
the expression of
PTP1B and T
cell protein tyrosine phosphatase (
TC-PTP)

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

insulin activates phosphoprotein phosphatase leading to
