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.
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 determine where repeating parts, such as the many vertebrae of snakes, will grow in a developing embryo or larva. [9] Pax-6, already mentioned, is a classic toolkit gene. [48] Although other toolkit genes are involved in establishing the plant bodyplan, [49] homeobox genes are also found in plants, implying they are common to all ...
The homeobox gene clusters studied by Ed Lewis were named the Hox genes, although many more homeobox genes are encoded by animal genomes than those in the Hox gene clusters. The homeotic-function of certain proteins was first postulated to be that of a "selector" as proposed by Antonio Garcia-Bellido . [ 11 ]

This gene is part of the A cluster on chromosome 7 and encodes a DNA-binding transcription factor which may regulate gene expression, morphogenesis, and cellular differentiation. The homeobox protein Hox-A1 may be involved in the placement of hindbrain segments in the proper location along the anterior-posterior axis during development. [8]
