Fig. 1.

Inferred amino acid sequence for the complete Patiria miniata bindin cDNA. Domains are distinguished by type face: signal sequence (gray), collagenlike (green), A (cyan), B (red), C (blue), core (bold). Preprobindin sequence (ending in the probable cleavage motif RARR) is underlined. Highly conserved cysteine residues in preprobindin are shown in bold italics. Repeats are numbered above each sequence. Arrows show location and direction of PCR primers (Table 1) used in RACE experiments or in amplification from cDNA or genomic DNA. Large arrowhead shows the location of a single 1005 bp intron in codon 959 (leucine). Boxes show peptide fractions identified in sperm by tandem mass spectrometry.
