Fig. 1. Comparison of the deduced amino acid sequence of eSRS21 with the sequence of Müllerian-inhibiting substance (MIS) from chicken (Eusèbe et al., 1996), human (Cate et al., 1986) and mouse (Münsterberg et al., 1991). This alignment was performed using Clustal W software (Thompson et al., 1994). Numbering of the amino acid residues relates to eSRS21. Red characters indicate residues that are conserved throughout all sequences. Grey characters indicate residues that are the same for 3/4 sequences. Asterisks indicate seven conserved cysteine residues. Dash represents a gap in the sequence introduced to maximise alignment; arrowhead indicates the signal sequence cleavage site. Underlined residues denote a possible N-glycosylation site.
