Checklist: Vertebrate homeo☐ genes
نویسندگان
چکیده
Up to now around 170 different homeobox genes have been cloned from vertebrate genomes. A compilation of the various isolates from mouse, chick, frog, fish and man is presented in the form of a concise checklist, including the designations from the original publications. Putative homologs from different species are aligned, and key characteristics of embryonic or adult expression domains, as well as mutant phenotypes are briefly indicated.

Homeobox genes and the vertebrate head.
Several Drosophila genes important in the control of embryonic development contain a characteristic sequence of DNA, known as the homeobox. Homeobox sequences are also present in a family of vertebrate genes, which may therefore have regulatory roles during vertebrate embryogenesis. In this article, data concerning the spatial patterns of vertebrate homeobox gene expression are discussed in rel...
متن کاملNovel murine homeo box gene on chromosome 1 expressed in specific hematopoietic lineages and during embryogenesis.
We describe here a new murine homeo box gene, denoted Hlx, which is expressed within specific hematopoietic lineages. The cDNA sequence indicates that Hlx differs markedly from known vertebrate homeo box genes, and linkage analysis of an interspecific murine backcross showed that it resides at a novel homeo box locus on the distal portion of mouse chromosome 1. The Hlx homeo domain is most simi...
متن کاملGradient fields and homeobox genes.
We review here old experiments that defined the existence of morphogenetic gradient fields in vertebrate embryos. The rather abstract idea of cell fields of organ-forming potential has become less popular among modern developmental and molecular biologists. Results obtained with antibodies directed against homeodomain proteins suggest that gradient fields may indeed be visualized at the level o...
متن کاملOrganization of mouse Iroquois homeobox genes in two clusters suggests a conserved regulation and function in vertebrate development.
Iroquois proteins comprise a conserved family of homeodomain-containing transcription factors involved in patterning and regionalization of embryonic tissues in both vertebrates and invertebrates. Earlier studies identified four murine Iroquois (Irx) genes. Here we report the isolation of two additional members of the murine gene family, Irx5 and Irx6. Phylogenetic analysis of the Irx gene fami...
متن کاملHeterotopic shift of epithelial-mesenchymal interactions in vertebrate jaw evolution.
Genes involved in late specification of the mandibular arch, the source of the vertebrate jaw, are expressed with similar patterns in the oral regions of chick and lamprey embryos. However, morphological comparisons indicate that apparently orthologous homeobox genes were expressed in different subdivisions of the ectomesenchyme in the two species. Therefore, the homology and gene expression of...
