Heat-shock protein of 90 kDa (HSP90) a molecular chaperone, associates with VEGFR2 in response to VEGF. The last 130 amino acids of VEGFR2 C-terminal portion are involved in the association of VEGFR2 with HSP90. HSP90 associated with VEGFR2 is involved in regulating the activity of a Rho-associated protein kinase (ROCK) that is required to phosphorylate FAK on residue S732 (Le Bouef et al. 2004, 2006).
