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.
The main interest in this set of genes stems from their unique behavior and arrangement in the genome. Hox genes are typically found in an organized cluster. The linear order of Hox genes within a cluster is directly correlated to the order in which they are expressed in both time and space during development. This phenomenon is called colinearity.
Hox genes are a subset of the homeobox genes. The Hox genes are often conserved across species, so some of the Hox genes of Drosophila are homologous to those in humans. In general, Hox genes play a role of regulating expression of genes as well as aiding in development and assignment of specific structures during embryonic growth.
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 ...
HOTAIR (for HOX transcript antisense RNA) [3] is a human gene located between HOXC11 and HOXC12 on chromosome 12.It is the first example of an RNA expressed on one chromosome that has been found to influence the transcription of the HOXD cluster posterior genes located on chromosome 2.
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]
The SHH gene is a member of the hedgehog gene family with five variations of DNA sequence alterations or splice variants. [37] SHH is located on chromosome seven and initiates the production of Sonic Hedgehog protein. [37] This protein sends short- and long-range signals to embryonic tissues to regulate development.
