Abstract
Three highly homologous homeobox genes (caupolican, araucan and mirror) have been identified in Drosophila. These genes belong to the novel Iroquois complex, which acts as a pre-pattern molecule in Drosophila neurogenesis. Recently several vertebrate Iroquois homologues (Irx) were isolated and found to be involved in pattern formation of various tissues. Here we report cytogenetic mapping of four human and five chicken Iroquois genes by FISH. Our findings revealed that vertebrate Irx genes are clustered at two different loci.
