MYB4

Gene

MYB4

Protein

Transcription repressor MYB4

Organism

Arabidopsis thaliana

Length

282 amino acids

Function

Transcription repressor involved in regulation of protection against UV. Mediates transcriptional repression of CYP73A5, the gene encoding trans-cinnamate 4-monooxygenase, thereby regulating the accumulation of the UV-protectant compound sinapoylmalate.

Organism

Oryza sativa subsp. japonica

Length

257 amino acids

Function

Transcriptional activator involved in cold stress response (PubMed:14675437, PubMed:20807373, PubMed:22246661). Regulates positively the expression of genes involved in reactive oxygen species (ROS) scavenging such as peroxidase and superoxide dismutase during cold stress. Transactivates a complex gene network that have major effects on stress tolerance and panicle development (PubMed:20807373).
