Abstract

The primary ITAM-containing signaling adapters, in osteoclast lineage cells, are DAP12 and the FcεRIγ chain (FcRγ). Each associates with specific immunoreceptors. DAP12 associates with the receptors TREM2 and SIRPβ1 [1], while FcRγ recognizes OSCAR [2, 3]. Both molecules also contain an ITAM motif, within their cytoplasmic domains, whose phosphorylated tyrosines provide a high-affinity binding site for Syk family kinases.
