Fcer1g Gene Summary [Mouse]

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). [provided by Alliance of Genome Resources, Apr 2025]

Protein Domains

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Fcer1g often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
