Possible modulation of Arabidopsis ETR1 N-terminal signaling by CTR1.

Plant signaling & behavior - 1 Oct 2012

Xie Fang, Qiu Liping, Wen Chi-Kuang

Abstract excerpt

The mitogen-activated protein kinase kinase kinase (MAPKKK) Constitutive Triple-Response1 (CTR1) plays a key role in mediating ethylene receptor signaling via its N-terminal interaction with the ethylene receptor C-terminal histidine kinase (HK) domain. Loss-of-function mutations of CTR1 prevent ethylene receptor signaling, and corresponding ctr1 mutants show a constitutive ethylene response phenotype. We...
