Annotation PubMed Id
It was shown that phosphatidic acid (PA) binds CTR1 and inhibits its kinase activity; Subsequent deletion analysis of CTR1's kinase domain revealed a novel PA-binding region at the C-terminus of the kinase. 18000017
Data demonstrate that CTR1 acts as a concentration-dependent repressor of a biosynthesis-dependent auxin gradient that modulates planar polarity in the root tip. 19448626
Results report the crystallization of the C-terminal protein kinase domain of CTR1 in its wild-type form and as a kinase-dead mutant, and show that wild-type crystals diffracted to 3 A resolution and the kinase-dead mutant to 2.5 A resolution. 21206040
Together with a front-to-front activation interface, the active protein kinase dimers thereby engage in interactions that promote CTR1-mediated cross talk between ethylene receptor clusters. 22155294
The roles of CTR1 and RTE1 in ETR1 N-terminal signaling, were evaluated. 22566492
Possible modulations of ETR1 N-terminal signaling with docking of CTR1 on the ETR1 HK domain, is reported. 22902695
Phosphorylation of EIN2 by CTR1 prevents EIN2 from signaling in the absence of ethylene, whereas inhibition of CTR1 upon ethylene perception is a signal for cleavage and nuclear localization of the EIN2 C terminus. 23132950
Genetic studies unveiled the existence of are1-1 mutation in the ctr1-1 mutant, as a second-site modifier which confers root-specific ethylene-resistance. 23740431
Protein phosphorylation plays a key role in ethylene signaling, which is mediated by the activities of ethylene receptors, CTR1, and RCN1. 24043427
Ethylene receptor/CTR1 signaling is regulated by ethylene in Arabidopsis thaliana 25814663
The dark submergence-sensitive phenotypes of loh mutants were rescued by a ctr1-1 mutation. Thus, our findings demonstrate that unsaturation of VLC ceramides is a protective strategy for hypoxic tolerance in Arabidopsis 25822663
Ethylene (ET) affects auxin signaling through the central regulator CTR1 and that fungal-derived compounds, such as indole-3-acetic acid and indole-3-acetaldehyde, induce MPK6 activity. 26067203
the roles of CTR1-related proteins appear to have functionally diversified during land-plant evolution. 26243614
