Most Pax genes contain a homeobox and a paired domain that also binds DNA to increase binding specificity, though some Pax genes have lost all or part of the homeobox sequence. [46] Pax genes function in embryo segmentation, nervous system development, generation of the frontal eye fields, skeletal development, and formation of face structures.
In evolutionary developmental biology, homeosis is the transformation of one organ into another, arising from mutation in or misexpression of certain developmentally critical genes, specifically homeotic genes. In animals, these developmental genes specifically control the development of organs on their anteroposterior axis. [1]
tinman, or tin is an Nk2-homeobox containing transcription factor first isolated in Drosophila flies. The human homolog is the Nkx2-5 gene. tinman is expressed in the precardiac mesoderm and is responsible for the differentiation, proliferation, and specification of cardiac progenitor cells.
Paralogous genes can shape the structure of whole genomes and thus explain genome evolution to a large extent. Examples include the Homeobox genes in animals. These genes not only underwent gene duplications within chromosomes but also whole genome duplications. As a result, Hox genes in most vertebrates are clustered across multiple ...

Hox genes, a subset of homeobox genes, are a group of related genes that specify regions of the body plan of an embryo along the head-tail axis of animals. Hox proteins encode and specify the characteristics of 'position', ensuring that the correct structures form in the correct places of the body. For example, Hox genes in insects specify ...

Homeobox protein Hox-A7 is a protein that in humans is encoded by the HOXA7 gene. [5] [6] [7] In vertebrates, the genes encoding the class of transcription factors called homeobox genes are found in clusters named A, B, C, and D on four separate chromosomes. Expression of these proteins is spatially and temporally regulated during embryonic ...
