Summary: 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 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). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
