Fig. 1. Amino acid sequences of chicken Edar, Eda and Edaradd. The inferred amino acid sequences of the chicken proteins are compared with their mouse orthologs. The valine and glutamine present in Eda-A1 and absent from Eda-A2, and the TRAF interaction consensus sequence (PXQXT) of Edaradd, are marked by asterisks. Death domains of Edar and Edaradd, and the furin cleavage site of Eda, are underlined.
