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.
Description
Recombinant Human CD89 Protein is expressed from Expi293 with His tag at the C-terminal. It contains Gln22-Asn227.
Target
CD89
Species
Human
Gene/Protein ID
NP_001991.1
Exact Sequence
Gln22-Asn227
Molecular Weight
The protein has a predicted MW of 24.6 kDa. Due to glycosylation, the protein migrates to 45-65 kDa based on the Tris-Bis PAGE result.
