title: A sea urchin homologue of ceh-19, an unusual homeobox-containing gene from a nematode.
abstract: When screening for homeobox-containing genes from the sea urchin Heliocidaris erythrogramma (He), we isolated an exon of a gene which appears to be a homologue of the homeobox-containing gene, ceh-19, of Caenorhabditis elegans (Ce). The predicted translation of the sea urchin sequence shows 77% identity and 92% similarity to the first 53 amino acids of the homeodomain of ceh-19. The ceh-19 gene exhibits an intron in an unusual location in the 3' end of the homeobox; the He gene shares this feature.
