LAT participate in NK-cell cytotoxicity against tumor cells downstream of CD16 and 2B4 signaling.
LAT is phosphorylated downstream of 2B4 and CD16
PMID:9489702, PMID:10072481, PMID:7523143
LAT is a substrate for ZAP-70, Syk protein tyrosine kinases in T cells and probably in NK cells.
PMID:11169415, PMID:10072481, PMID:8649391
Tyrosine phosphorylation of LAT led to the recruitment of intracytoplasmic signaling molecules including phospholipase Cgamma and Grb2
and activation of phosphatidylinositol pathway.

PTP-1C (SHP-1) binds to and dephosphorylates pp36 (LAT) and disrupted the ability of pp36 (LAT) to associate with Grb2 downstream of KIR3DL1.
PMID:10781611
The adapter protein LAT enhances fcgamma receptor-mediated signal transduction in myeloid cells.
Co-immunoprecipitation experiments revealed a constitutive association of p36 LAT with both FcgammaRI and FcgammaRIIa immunoprecipitates, and an activation-induced association of LAT with PLCgamma1, Grb2, and the p85 subunit of phosphatidylinositol 3-kinase.
bone marrow-derived macrophages from LAT-deficient mice displayed reduced phagocytic efficiency in comparison to the macrophages from wild-type mice.
