POU Class
Families List  Genes List
Proteins encoded by POU class homeobox genes have a ~75 amino acid POU-specific domain (named from the mammalian genes Pit1 (now Pou1f1), OCT1 and OCT2 (now POU2F1 and POU2F2), and nematode unc-86) N-terminal to a 60-amino acid homeodomain. Together the two domains are known as the bipartite POU domain. There are 15 genes with this structure in the human genome, plus a 16th gene (HDX) that possesses a homeodomain related to POU-type homeodomains but lacking a POU-specific domain. Including the divergent HDX gene, this gene class has 16 human genes in seven gene families; there are also eight pseudogenes (Ryan and Rosenfeld 1997, Holland et al. 2007). Amphioxus has seven genes in six families (Takatori et al. 2008).
