Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables IgE receptor activity; identical protein binding activity; and immunoglobulin 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 immune response-regulating cell surface receptor signaling pathway; positive regulation of cytokine production; and positive regulation of immune effector process. Located in external side 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 epsilon receptor Ig).
