The Pfam alignment is truncated at the C-terminus and does not include the final cysteine defined in Callebaut et al [2]. This is to stop the family overlapping with other domains.

1: EMI, a novel cysteine-rich domain of EMILINs and other extracellular proteins, interacts with the gC1q domains and participates in multimerization. Doliana R, Bot S, Bonaldo P, Colombatti A; FEBS Lett 2000;484:164-168. PMID:11068053

2: EMI domains are widespread and reveal the probable orthologs of the Caenorhabditis elegans CED-1 protein. Callebaut I, Mignotte V, Souchet M, Mornon JP; Biochem Biophys Res Commun 2003;300:619-623. PMID:12507493
