Identification of the zebrafish Cirhin homolog.

<p>(<b>A</b>) Protein sequence alignments of human CIRHIN and zebrafish Cirhin. Identical residues are shaded black, and similar residues are shaded grey. Zebrafish Cirhin contains 685 amino acids, and is 54% identical and 72% similar to the human protein, with identity at the arginine residue mutated in NAIC (red arrowheads). (<b>B</b>) Synteny analyses of zebrafish chromosome 18 and human chromosome 16 near the <i>cirh1a</i> and <i>CIRH1A</i> loci. Diagonal lines indicate conserved syntenic relationships.
