abstract：:The presence of homoeo box sequences in the genomes of vertebrates has suggested that these metazoans possess the equivalent of the homoeotic genes that have a key role in regulating the development of the fruitfly Drosophila melanogaster. We report here that a novel murine homoeo box-containing gene is expressed in e...
