Fig. 4. Multiple sequence alignment of Snky and related proteins. Three regions, denoted a, b and c, are the most highly conserved among Snky family members and are aligned here. Their locations in Snky are shown in Fig. 3. The sequence of Snky (D. melanogaster), the mouse (M. musculus) and human proteins are based on full-length cDNAs. The mosquito (A. aegypti) and zebrafish (D. rerio) sequences are based on conceptual translations of predicted genes.
