DNAX accessory molecule-1 (DNAM-1, CD226) isa cell surface molecule capable of enhancing cytolytic activity and cytokine production in NK cells. Its ligands represented by two members of the nectin family: the poliovirus receptor (PVR CD155) and nectin-2 (CD112). Both molecules can be highly expressed in tumor cell lines, including carcinomas, melanomas and neuroblastomas.
DNAM-1 does not associate with any ITAM-bearing molecule but, after receptor crosslinking, its
intracellular domain gets phosphorylated and delivers an intracellular signal. PKC induces phosphorylation of the Ser329 and probably FYN mediates phosphorylation of DNAM-1 at tyrosine residue 322.

DNAM1 induces VAV1 pathway probably via LCP2 (SLP76) . It demonstrate synergy with 2B4 in activation of vav1 pathway.
DNAM1 signaling stimulate Ca2+??mobilization provably via PLC-GAMMA2 and induces ERK pathway probably via VAV1.
