Anti-FCE1A antibodies enable researchers to detect and measure the FCE1A antigen in biological samples. This target is a reported synonym of the FCER1A gene, which encodes Fc epsilon receptor Ia. This protein is known to function in receptor-mediated signaling pathways, among other biological roles. The human version of FCE1A has a canonical amino acid length of 257 residues and a protein mass of 29.6 kilodaltons. It is reported to be localized in the cell membrane of cells and notably expressed in many tissues, such as the cervix, tonsil, and caudate. This target antigen may also be known as FCERIA.
