myb domain protein 18
NCBI Summary
LAF1 is a R2R3-MYB transcription factor and positive regulator of the phyA photoresponse. Interaction of LAF1 with HFR1 stabilize the proteins against ubiquitination by COP1(AT2G32950) and subsequent degrations. Mutants have an elongated hypocotyl specifically under far-red light but retain wild-type responses to other light wavelengths.

UniProt Comments
Transcription factor that promotes photomorphogenesis in the light by participating in the transmission of phytochrome A (phyA) signals to downstream responses (PubMed:11581165, PubMed:19482971). Probably acts by activating expression of light-induced genes. In darkness, its degradation prevents the activation of light-induced genes (PubMed:11581165).
