Cordon-bleu ubiquitin-like domain
The Cordon-bleu protein domain is highly conserved among vertebrates. The sequence contains three repeated lysine, arginine, and proline-rich regions, the KKRAP motif. The exact function of the protein is unknown but it is thought to be involved in mid-brain neural tube closure. It is expressed specifically in the node. This domain has a ubiquitin-like fold.
