Collapsin response mediator protein 1, encoded by the CRMP1 gene, is a human protein of the CRMP family. [5]
This gene encodes a member of a family of cytosolic phosphoproteins expressed exclusively in the nervous system. The encoded protein is thought to be a part of the semaphorin signal transduction pathway implicated in semaphorin-induced growth cone collapse during neural development. Alternative splicing results in multiple transcript variants. [5]
CRMP1 mediates reelin signaling in cortical neuronal migration. [6] Mice deficient in CRMP1 exhibit impaired long-term potentiation and impaired spatial learning and memory. [7]

Collapsin response mediator protein family or CRMP family consists of five intracellular phosphoproteins of similar molecular size and high (50–70%) amino acid sequence identity. CRMPs are predominantly expressed in the nervous system during development and play important roles in axon formation from neurites and in growth cone guidance and collapse through their interactions with microtubules. Cleaved forms of CRMPs have also been linked to neuron degeneration after trauma induced injury.
