| 1603318 | FCMR | Fc mu receptor | Fc receptors specifically bind to the Fc region of immunoglobulins (Igs) to mediate the unique functions of each Ig class. FAIM3 encodes an Fc receptor for IgM (see MIM 147020) (Kubagawa et al., 2009 [PubMed 19858324]; Shima et al., 2010 [PubMed 20042454]).[supp lied by OMIM, Jul 2010] | 1 | 206903317 | 206923196 | Human | 109 | description , old_gene_symbol | gene, protein-coding, VALIDATED [RefSeq] |
| 1622299 | Fcmr | Fc fragment of IgM receptor | Enables IgM binding activity. Involved in humoral immune response mediated by circulating immunoglobulin; immunoglobulin transcytosis in epithelial cells; and regulation of B cell receptor signaling pathway. Acts upstream of or within negative regulation of extrinsic apoptotic signaling pathway and negative regulation of lymphocyte apoptotic process. Located in external side of plasma membrane and trans-Golgi network membrane. Orthologous to human FCMR (Fc mu receptor).
