Fig. 1. Derrière protein sequence and alignments. Amino acid residues are shown. Numbers at left indicate amino acid positions. (A) Derrière protein sequence. Arrow indicates signal sequence cleavage site predicted by von Heijne algorithm. Maturation cleavage signal (RAKR) is boxed. These four amino acids are substituted with GVDG in Cm-Derrière. The mature region of Derrière protein is underlined. The seven cysteines within the mature region are underscored with solid bars. (B) Alignment of Derrière protein sequence to Xenopus Vg1 (Vg1), zebrafish Vg1 (zVg1), chicken Vg1 (CVg1) and incomplete newt Vg1 (nVg1). Consensus amino acid residues in proteins are shaded. Sequence gaps introduced for optimal protein alignment are indicated by dashes. The percentage identities between full-length Derrière and other Vg1-related proteins are 56% (xVg1), 51% (cVg1) and 50% (zVg1), with mature region identities of 79% (xVg1), 73% (cVg1) and 76% (zVg1).
