General annotation (Comments)

Function	Associates with a variety of FcR alpha chains to form a functional signaling complex. Regulates several aspects of the immune response. The gamma subunit has a critical role in allowing the IgE Fc receptor to reach the cell surface. Also involved in collagen-mediated platelet activation and in neutrophil activation mediated by integrin. Ref.3
Subunit structure	IgE Fc receptor is a tetramer of an alpha chain, a beta chain, and two disulfide linked gamma chains. The gamma chain from Fc-epsilon-Ri are also subunits of other Fc receptors like FCGR1A. Associated with CLEC6A By similarity. Interacts (via ITAM domain) with SYK (via SH2 domains); activates SYK, mediating neutrophils and macrophages integrin-mediated activation By similarity. Interacts with CLEC4E. Ref.3 Ref.6
Subcellular location	Cell membrane; Single-pass type I membrane protein Ref.3.
Sequence similarities	Belongs to the CD3Z/FCER1G family. Contains 1 ITAM domain.
