CERS Class
Families List  Genes List
The CERS (or LASS) homeobox gene class is highly unusual and encodes proteins that seem to be transmembrane in nature (Mizutani and Kihara 2005; Pewzner-Jung et al. 2006). The function of the homeodomain in these proteins is unknown. There are six CERS (ceramide synthase) genes in the human genome, but only five of these include a homeobox sequence and are therefore included in the CERS homeobox gene class (Holland et al. 2007). Amphioxus has a single CERS homeobox gene.
