High impact information on Crmp1

  • Molecular manipulations of dynamin-like GTPases Drp1 and OPA1 that reduce dendritic mitochondria content lead to loss of synapses and dendritic spines, whereas increasing dendritic mitochondrial content or mitochondrial activity enhances the number and plasticity of spines and synapses [1].
  • Rat CRMP-2/TOAD-64 is most closely related to chick CRMP-62 and is the most widely expressed CRMP within the nervous system [2].
  • Therefore, inhibition of GSK3 alters phosphorylation of all CRMP isoforms; however, individual isoforms can be differentially regulated by their respective priming kinase [3].
  • Cypin contains zinc binding, collapsin response mediator protein (CRMP) homology, and PSD-95, Discs large, zona occludens-1 binding domains [4].
  • In addition, cypin binds tubulin via its CRMP homology domain to promote microtubule assembly [4].
 

Biological context of Crmp1

 

Anatomical context of Crmp1

  • In the N1E-115 cells, CRMP-2 has the most potent neurite elongation activity among the CRMP family members [7].
  • Although purified brain CRMP does not hydrolyze several DHPase substrates, it is likely that a related activity accounts for CRMP participation in neuronal growth cone signaling [5].
  • Both the zinc binding and CRMP homology domains are needed for dendrite patterning [4].
  • Mitochondria in DRG neurons undergo hyperglycemic mediated injury through Bim, Bax and the fission protein Drp1 [8].
  • The analysis implicates agrin and two members of the collapsin response-mediated protein (CRMP) family in the switch from precursors to Schwann cells, and synuclein-1 and alphaB-crystallin in peripheral nerve myelination [9].
