Fcer1a Gene Summary [Rat]
Predicted to enable IgE binding activity and high-affinity IgE receptor activity. Predicted to be involved in several processes, including eosinophil degranulation; type 2 immune response; and type I hypersensitivity. Predicted to act upstream of or within several processes, including leukotriene biosynthetic process; positive regulation of immune effector process; and positive regulation of macromolecule metabolic process. Predicted to be located in cell surface and plasma membrane. Predicted to be active in external side of plasma membrane. Orthologous to human FCER1A (Fc epsilon receptor Ia).

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 rat Fcer1a often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
