Entrez Gene Summary for FCGR2B Gene

  • The protein encoded by this gene is a low affinity receptor for the Fc region of immunoglobulin gamma complexes. The encoded protein is involved in the phagocytosis of immune complexes and in the regulation of antibody production by B-cells. Variations in this gene may increase susceptibilty to systemic lupus erythematosus (SLE). Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jun 2010]

GeneCards Summary for FCGR2B Gene

FCGR2B (Fc Fragment Of IgG, Low Affinity IIb, Receptor (CD32)) is a Protein Coding gene. Diseases associated with FCGR2B include chronic polyneuropathy and systemic lupus erythematosus. Among its related pathways are Class I MHC mediated antigen processing and presentation and Phospholipase-C Pathway. GO annotations related to this gene include IgG binding. An important paralog of this gene is FCRL2.

UniProtKB/Swiss-Prot for FCGR2B Gene

  • Receptor for the Fc region of complexed or aggregated immunoglobulins gamma. Low affinity receptor. Involved in a variety of effector and regulatory functions such as phagocytosis of immune complexes and modulation of antibody production by B-cells. Binding to this receptor results in down-modulation of previous state of cell activation triggered via antigen receptors on B-cells (BCR), T-cells (TCR) or via another Fc receptor. Isoform IIB1 fails to mediate endocytosis or phagocytosis. Isoform IIB2 does not trigger phagocytosis

FCG2B_HUMAN
  • Note=A chromosomal aberration involving FCGR2B is found in a follicular lymphoma. Translocation t(1;22)(q22;q11). The translocation leads to the hyperexpression of the receptor. This may play a role in the tumor progression.
  • Systemic lupus erythematosus (SLE) [MIM:152700]: A chronic, relapsing, inflammatory, and often febrile multisystemic disorder of connective tissue, characterized principally by involvement of the skin, joints, kidneys and serosal membranes. It is of unknown etiology, but is thought to represent a failure of the regulatory mechanisms of the autoimmune system. The disease is marked by a wide range of system dysfunctions, an elevated erythrocyte sedimentation rate, and the formation of LE cells in the blood or bone marrow. {ECO:0000269 PubMed:12115230, ECO:0000269 PubMed:20385827}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
