Anti-CD64A antibodies enable researchers to detect and measure the CD64A antigen in biological samples. This target is a reported synonym of the FCGR1A gene, which encodes Fc gamma receptor Ia. This protein is known to function in receptor-mediated signaling pathways and immune response pathways, among other biological roles. The human version of CD64A has a canonical amino acid length of 374 residues and a protein mass of 42.6 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cell membrane of cells. Other names for this target antigen include CD64 and FCG1.
