Upon engagement of activating receptors, the tyrosine-containing adapters undergo tyrosine phosphorylation mediated by Src family kinases (SFKs)??.
Cross-linking of Nkp30 or Nkp46 or NKp44 resulted in strong tyrosine phosphorylation of LCK anf FYN kinases.
PMID:12740575
Src kinaze LCK participate in activation of NKG2D signaling and induction of PLCG phosphorylation, probably via DAP10 phosphorylation.
PMID:9751747, PMID:8986721
LCK phosphorylates KIR receptors in NK cells downstream of HLA binding.
PMID:22513334
Probably activated SHP-1 binds to Lck (through the Lck SH2 domain), which leads to dephosphorylation and inactivation of Lck by SHP-1 in NK cells (demonstrated in T cells).
PMID:9751747
KIR2DL3, KIR2DL1, KIR2DS4, KIR3DL1, KIR3DL2, KIR2DL4 interact with SHP-2 in NK cells
and probably are phosphorylated by LCK (directly demonstrated for KIR2DL3 only).
(CL6 = KIR2DL3,CL42 =KIR2DL1, CL39 = KIR2DS4, NKAT3= KIR3DL1, NKAT4 = KIR3DL2,KIR103AS=KIR2DL4)
