Identification of a homeobox-containing gene located betweenlin-45andunc-24on chromosome IV in the nematodeCaenorhabditis elegans

Abstract
Using two primers corresponding to helix 1 and helix 3 regions in the homeodomain, we subjected genomic DNA from Caenorhabditis elegans to amplification by the polymerase chain reaction. Sequence analysis of the amplified products revealed a new homeobox-containing gene, designated ceh-19. This gene was located between lin-45 and unc-24 on chromosome IV where no homeogene has previously been mapped.
