Nkp46 controls NK cytolitic activity via PI3K /RAC1/PAK1/MEK??/ERK pathway, probably throught SYK
PMID:11907067, PMID:11062502
RAC1 activates PAK1 downstream of SYK and PI3K and upstream of ERK and MEK.
PMID:12885870
Engagement of the beta2 integrin LFA-1 on NK cells by intercellular adhesion molecule (ICAM)-1 led to a tyrosine phosphorylation of Vav1 that was not sensitive to cholesterol depletion and to inhibition of actin polymerization. Vav1 phosphorylation was blocked by an inhibitor of Src-family kinases, and correlated with activation of its downstream effector PAK1.
