Evidence: SHP-2 binds to these residues on the leptin receptor via different sites [56]. Binding of SHP-2 to Y985 occurs via a SH2 domain and results in the activation of the enzyme, whereas Y974 likely associates with the active site of the enzyme SHP-2 binds to phosphotyrosine 986, becomes activated and can thus down-regulate further tyrosine phosphorylation-dependent leptin signalling such as STAT3 activation in the hypothalamus.

Banks et al., J Biol Chem 2000
:
By using this system, we confirm that two tyrosine residues in the intracellular domain of murine LRb become phosphorylated to mediate LRb signaling ; Tyr ( 985 ) controls the tyrosine phosphorylation of
SHP-2 , and Tyr ( 1138 )
controls STAT3 activation
Gunaje et al., Biochem Biophys Res Commun 2001
:
Involvement of tyrosine phosphatase
PTP1D in the inhibition of interleukin-6 induced
Stat3 signaling by alpha-thrombin ... Pretreatment of cells with a phosphatase inhibitor reversed the inhibitory actions of alpha-thrombin, suggesting a
role for
PTP1D in alpha-thrombin mediated inhibition of IL-6 induced
Stat3 signaling
Lundin Brockdorff et al., Cytokine 2002
(MAP Kinase Signaling System...) :
SHP2 regulates IL-2 induced MAPK activation, but not
Stat3 or Stat5 tyrosine phosphorylation, in cutaneous T cell lymphoma cells ... Furthermore, the results indicate that
SHP2 may not be
involved in the activation of
Stat3 or Stat5 in CTCL cells
Pai et al., Biochem Biophys Res Commun 2005
(Stomach Neoplasms) :
While JAK inhibition with AG490 significantly reduced leptin induced ERK2,
STAT3 phosphorylation, and cell proliferation,
SHP2 inhibition only partially
reduced cancer cell proliferation
Han et al., Gastroenterology 2005
(Colitis...) :
SHP-2 , through binding to the glycoprotein 130 signaling receptor, negatively
regulates STAT3 activation
Wang et al., Mol Biol Cell 2006
:
Expression of catalytically inactive
SHP-2 in DDR1 transfected cells
restored the tyrosine phosphorylation of
Stat3 and cell migration ... Together, these results demonstrate that
SHP-2 is
required for the DDR1 induced suppression of Stat1 and
Stat3 tyrosine phosphorylation, cell migration, and branching tubulogenesis
Duechting et al., J Virol 2008
(Inflammation) :
Analysis of the transcriptional activation of target genes revealed that
NS1 induced
STAT3 signaling was associated with upregulation of genes involved in immune response ( e.g., the IFNAR1 and IL-2 genes ) and downregulation of genes associated with viral defense ( e.g., the OAS1 and TYK2 genes ) ... The
NS1 induced upregulation of
STAT3/PIAS3 in the absence of STAT1 phosphorylation and the lack of SOCS1/SOCS3 activation may contribute to the mechanisms by which B19 evades the immune response and establishes persistent infection in human endothelial cells
Park et al., Free Radic Biol Med 2009
:
In the presence of H ( 2 ) O ( 2 ),
SHP-2 formed a complex with STAT-3 and
reduced the steady-state
STAT-3 phosphorylation level
