TALE Class
Families List  Genes List
Homeobox genes in the TALE class (TALE = Three Amino Acid Loop Extension) encode proteins with a 63-amino acid homeodomain, with the short extension located between alpha helices 1 and 2. The TALE group is sometimes given the rank of 'superclass' and divided into several classes by the presence of distinct domains outside of the homeodomain - IRX, MKX, MEIS, PBC and TGIF (Bürglin 2005, Bürglin and Mukherjee 2007). We group these genes as one class divided into six gene families. There are 20 human TALE homeobox genes and 10 pseudogenes (Holland et al. 2007); amphioxus has 9 TALE homeobox genes (Takatori et al. 2008).
