background	CD89 (Fc alphaRI) is the human myeloid IgA Fc receptor expressed on cells, such as neutrophils, eosinophils and monocytes/macrophages.CD89 is a transmembrane glycoprotein that binds both subclasses of IgA in all its molecular forms (i.e. monomeric, dimeric and secretory IgA) via a region of its membrane-distal EC1 domain.
molecular weight	The protein has a predicted MW of 24.6 kDa. Due to glycosylation, the protein migrates to 45-65 kDa based on Tris-Bis PAGE result.
available size	100 µg, 500 µg
endotoxin	Less than 1EU per μg by the LAL method.

Protein names Immunoglobulin alpha Fc receptor (IgA Fc receptor) (CD antigen CD89)
Mass 32265Da
Function Binds to the Fc region of immunoglobulins alpha. Mediates several functions including cytokine production. {ECO:0000269\|PubMed:12768205}.
Subellular location [Isoform A.1]: Cell membrane; Single-pass type I membrane protein.; [Isoform A.2]: Cell membrane; Single-pass type I membrane protein.; [Isoform A.3]: Cell membrane; Single-pass type I membrane protein.; [Isoform B]: Secreted.; [Isoform B-delta-S2]: Secreted.
Tissues Isoform A.1, isoform A.2 and isoform A.3 are differentially expressed between blood and mucosal myeloid cells. Isoform A.1, isoform A.2 and isoform A.3 are expressed in monocytes. Isoform A.1 and isoform A.2 are expressed in alveolar macrophages; however only one isoform is expressed at alveolar macrophages surfaces. {ECO:0000269\|PubMed:8666819, ECO:0000269\|PubMed:8836118}.
Structure Associates with the Fc epsilon RI gamma 2 receptor inducing tyrosine phosphorylation of gamma 2. {ECO:0000269\|PubMed:12768205, ECO:0000269\|PubMed:7522255}.; (Microbial infection) Interacts with Staphylococcus aureus protein SSL11. {ECO:0000269\|PubMed:18045383}.
