CRMP3, or Dihydropyrimidinase like 4, is a human gene encoded by DPYSL4. It may also be known as: Dihydropyrimidinase-related protein 4; DRP-4; Collapsin response mediator protein 3; CRMP-3; UNC33-like phosphoprotein 4; ULIP-4; ULIP4; dihydropyrimidinase-like 4. The encoded protein has an amino acid length of 572 and a mass of 61.9 kDa. Other isoforms may exist. CRMP3 is a member of the DHOase family, Hydantoinase/dihydropyrimidinase subfamily. Homologs of this gene exist in other organisms, including: Mouse, Frog.
