Alignment of the ectodysplasin 1 (ED1-A1) amino acid sequences of cattle, human, and mouse. The interrupted (Gly-X-Y)19 repeat is underlined. Arrows mark the amino acids 308E and309V that are absent from the ED1-A2 isoform. Note the extremely high-sequence conservation of the proteins in the C-terminal region that harbors the TNF-like signaling domain.
