Insights into the oligomerization of CRMPs: Crystal structure of human collapsin response mediator protein 5.
Collapsin response mediator proteins (CRMPs) are cytosolic homo- and/or hetero-tetrameric phosphoproteins crucial for neuronal development and repair. We determined the crystal structure of human CRMP-5, revealing a homo-tetramer assembly similar to that of other CRMPs. Solution studies indicate that subunit interactions in CRMP-5 and CRMP-1 homo-tetramers are weaker compared with CRMP-2, and that divalent cations, Ca2+ and Mg2+, destabilize them further.
