Anti-EDAR-associated death domain antibodies enable researchers to detect and measure the EDAR-associated death domain antigen in biological samples. This target is a reported synonym of the EDARADD gene, which encodes EDAR associated via death domain. This protein is known to function in cell differentiation and signal transduction pathways, among other biological roles. The human version of EDAR-associated death domain has a canonical amino acid length of 215 residues and a protein mass of 24.8 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cytoplasm of cells. Other names for this target antigen include ectodysplasin-A receptor-associated adapter protein and EDAR associated death domain.
