Fcmr Gene Summary [Rat]

Predicted to enable IgM binding activity; high-affinity IgM receptor activity; and polymeric immunoglobulin binding activity. Predicted to be involved in several processes, including Fc receptor-mediated immune complex endocytosis; humoral immune response mediated by circulating immunoglobulin; and regulation of B cell receptor signaling pathway. Predicted to act upstream of or within negative regulation of extrinsic apoptotic signaling pathway and negative regulation of lymphocyte apoptotic process. Predicted to be located in several cellular components, including bounding membrane of organelle; external side of plasma membrane; and trans-Golgi network membrane. Predicted to be active in plasma membrane. Orthologous to human FCMR (Fc mu receptor). [provided by Alliance of Genome Resources, Jul 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 rat Fcmr often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
