Description

FCAR (Fc alpha receptor) or CD89 is a single-pass type I transmembrane protein belonging to the immunoglobulin (Ig) superfamily (IgSF).  ICD89 contains two Ig-like C2-type domains in the extracellular region.  CD89 binds to the Fc region of immunoglobulins alpha (IgA) and mediates several functions including cytokine production. CD89 associates with ITAM­containing signaling subunit FcRγ (Ig epsilon receptor subunit gamma) to form a functional signaling complex.  CD89 is present on the surface of myeloid lineage cells such as neutrophils, monocytes, macrophages, and eosinophils, where it mediates immunologic responses to pathogens.  CD89 recognizes IgA-opsonized targets and triggers several immunologic defense processes, including phagocytosis, antibody-dependent cell-mediated cytotoxicity (ADCC), and stimulation of the release of inflammatory mediators. There are multiple alternatively splicing variants encoding different isoforms of CD89.
