Abstract
Homeobox genes represent a class of transcription factors that play key roles in the regulation of embryogenesis and development. Here we report the identification of a homeobox-containing gene family that is highly conserved at both the nucleotide and amino acid levels in a diverse number of species. These species encompass both vertebrate and invertebrate phylogenies, ranging from Homo sapiens to Drosophila melanogaster. In humans, at least two homeobox sequences from this family were identified representing a previously reported member of this family as well as a novel homeobox sequence that we physically mapped to the 10q25.2–q26.3 region of human Chromosome (Chr) 10. Multiple members of this family were also detected in three additional vertebrate species including Equus caballus (horse), Gallus gallus (Chicken), and Mus musculus (mouse), whereas only single members were detected in Tripneustes gratilla (sea urchin), Petromyzon marinus (lamprey), Salmo salar (salmon), Ovis aries (sheep), and D. melanogaster (fruit fly).
