Source Description
UniProtAtypical bHLH transcription factor probably unable to bind DNA. Negatively regulates brassinosteroid signaling. {ECO:0000269|PubMed:20023194}.
UniProtbHLH transcription factor that binds DNA on specific sequence 5'-CANNTG-3' in target gene promoters (PubMed:24009530). Negatively regulates brassinosteroid signaling (PubMed:20023194). Together with BHLH148/RITF1, regulates the transcription of several genes involved in the detoxification of reactive oxygen species (ROS) generated by salt (NaCl) stress. Confers tolerance to salt and to the oxidative stress-inducing reagents hydrogen peroxide H(2)O(2) and methyl viologen (MV) (PubMed:24009530). {ECO:0000269|PubMed:20023194, ECO:0000269|PubMed:24009530}.
