High impact information on Itsn1

 

Biological context of Itsn1

 

Anatomical context of Itsn1

  • In platelet-derived growth factor-stimulated Swiss 3T3 cells, intersectin co-localizes with CdGAP and inhibits its GAP activity toward Rac1 [7].
 

Associations of Itsn1 with chemical compounds

  • Thus, we propose a model in which intersectin binding results in a change of CdGAP conformation involving the proline-rich domain that leads to the inhibition of its GAP activity [7].
  • Cloning of full-length cDNAs revealed that EHSH1 is composed of an N-terminal region with two EH domains, a central region that is enriched in lysine, leucine, glutamate, arginine, and glutamine (KLERQ domain), and a C-terminal region comprised of five SH3 domains [4].
