The structure of Arabidopsis thaliana OST1 provides insights into the kinase regulation mechanism in response to osmotic stress.

Journal of molecular biology - 18 Nov 2011

Yunta Cristina, Martínez-Ripoll Martín, Zhu Jian-Kang, Albert Armando

Abstract excerpt

SnRK [SNF1 (sucrose non-fermenting-1)-related protein kinase] 2.6 [open stomata 1 (OST1)] is well characterized at molecular and physiological levels to control stomata closure in response to water-deficit stress. OST1 is a member of a family of 10 protein kinases from Arabidopsis thaliana (SnRK2) that integrates abscisic acid (ABA)-dependent and ABA-independent signals to coordinate the cell response to osmotic...
