PROS Class
Families List  Genes List
Genes in the PROS homeobox class (named after the Drosophila gene pros) encode proteins with a ~100-amino acid PROS domain C-terminal to an atypical and highly divergent 63-amino acid homeodomain. The additional three amino acids are between helices 2 and 3, whereas in TALE genes they are between helices 1 and 2. The human genome has two PROS homeobox genes, in a single gene class; amphioxus has a single representative.
