Fcer1g - Fc receptor, IgE, high affinity I, gamma polypeptide

Enables IgE receptor activity; IgG binding activity; and identical protein binding activity. Contributes to IgE binding activity. Involved in several processes, including cell surface receptor signaling pathway; positive regulation of interleukin-4 production; and serotonin secretion by platelet. Acts upstream of or within several processes, including leukocyte differentiation; positive regulation of cytokine production; and positive regulation of immune response. Located in external side of plasma membrane. Is integral component of plasma membrane. Part of Fc-epsilon receptor I complex. Is expressed in central nervous system; gut; male reproductive gland or organ; and retina. Orthologous to human FCER1G (Fc fragment of IgE receptor Ig).
