Anti-EDA3 antibodies enable researchers to detect and measure the EDA3 antigen in biological samples. This target is a reported synonym of the EDAR gene, which encodes ectodysplasin A receptor. This protein is known to function in the apoptotic pathway and cell differentiation, among other biological roles. The human version of EDA3 has a canonical amino acid length of 448 residues and a protein mass of 48.6 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the membrane of cells and widely expressed in many tissue types.
