Structural highlights
Function
[DPYL2_HUMAN] Plays a role in neuronal development and polarity, as well as in axon growth and guidance, neuronal growth cone collapse and cell migration. Necessary for signaling by class 3 semaphorins and subsequent remodeling of the cytoskeleton (By similarity). Plays a role in neuron projection morphogenesis.[1] [2]

Publication Abstract from PubMed
Axonal growth cone guidance is a central process in nervous system development and repair. Collapsin response mediator protein 2 (CRMP-2) is a neurite extension-promoting neuronal cytosolic molecule involved in the signalling of growth inhibitory cues from external stimuli, such as semaphorin 3A and the myelin-associated glycoprotein. We have determined the crystal structure of human tetrameric CRMP-2, which is structurally related to the dihydropyriminidases; however, the active site is not conserved. The wealth of earlier functional mapping data for CRMP-2 are discussed in light of the three-dimensional structure of the protein. The differences in oligomerisation interfaces between CRMP-1 and CRMP-2 are used to model CRMP-1/2 heterotetramers.
