What pLDDT means and how to read it

Function

Transcription factor that promotes photomorphogenesis in light. Acts downstream of the light receptor network and directly affects transcription of light-induced genes. Specifically involved in the blue light specific pathway, suggesting that it participates in transmission of cryptochromes (CRY1 and CRY2) signals to downstream responses. In darkness, its degradation prevents the activation of light-induced genes

Subunit structure

Heterodimer; heterodimerizes with HY5 via the leucine-zipper domains. Interacts with COP1 WD40 domain (PubMed:12023303). Interacts with BBX24/STO and BBX25/STH (PubMed:23733077)
