Amino acid sequence of the peptides used in this study, as well as the corresponding sequence motifs in human and squid NSF. Residue numbers are indicated on the top of the human NSF sequences. Boxes indicate residues that are identical between the human and squid sequences. Arrows show amino acid differences between the NSF-3 and hu-NSF-3 peptides. The 19-mer hu-NSF-3 peptide is identical to the human NSF sequence from 265 to 283.
