The ITAM can be part of the same polypeptidic chain that engages the ligand, as in the case of Fc??RIIA and Fc??RIIC, or of a separate ?? subunit that associates noncovalently with the ligand-binding subunit of the receptor, as in the case of Fc??RI and Fc??RIIIA. Upon receptor clustering, the ITAM associates with and becomes phosphorylated by Hck, Lyn (33, 34), and/or Fgr (35).

Hck, Lyn binds to Fc_gamma_RII (CD32) and phosphorylates it in monocytes.

Hck, Lyn binds to Fc_gamma_RI (cd64) in monocytes and probably
phosphorylate ignal transducing gamma subunit of the high-affinity IgE receptor (Fc epsilon RI gamma).
Induction of cytoplasmic protein tyrosine phosphorylation by Fc gamma RI cross-linking is known to be important in mediating Fc gamma RI-coupled effector functions.
Probably these kinases activate also IgE receptors directly and FCAR and Fc_gamma_RIII complexes with Fc epsilon RI gamma.
