ANTP Class
Families List  Genes List
The ANTP class is the largest of the homeobox gene classes in animal genomes. Thus far, these genes have only been found in animals. The ANTP class derives its name from (but is not an abbreviation for) the Antennapedia (Antp) gene of Drosophila. Although the best known ANTP class genes are the Hox genes, these comprise a minority of ANTP class genes. The human and mouse genomes each have 39 HOX genes, amongst a total of 100 ANTP genes (Holland et al. 2007; Zhong and Holland, 2011); there are also 19 ANTP pseudogenes described in the human genome and 2 in mouse. The amphioxus genome has 60 ANTP genes including 15 Hox genes (Takatori et al. 2008); Drosophila melanogaster has 47 ANTP class genes.

Following Holland et al. (2007) we subdivide the ANTP class into numerous gene families (e.g. 37 families in human); these are sometimes grouped into two relatively well-supported subclasses (HOXL and the NKL subclasses, meaning Hox-like and NK-like), although a few genes are hard to place in either the HOXL and NKL groups; another suggestion is to divide the class on the basis of chromosomal position (Hox-linked and NK-linked; Ferrier 2010).
