CRMP1 encodes the human gene, Collapsin response mediator protein 1. It may also be known as: Dihydropyrimidinase-related protein 1; CRMP-1; Unc-33-like phosphoprotein 3; ULIP-3; DPYSL1. The encoded protein has an amino acid length of 572 and a mass of 62.2 kDa. Other isoforms may exist. CRMP1 is a member of the DHOase family, Hydantoinase/dihydropyrimidinase subfamily. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
