== Function == | |||
[https://www.uniprot.org/uniprot/LVHTH_ERYLH LVHTH_ERYLH] Has reversible, light-dependent DNA-binding activity. Upon illumination an internal FMN-protein adduct is formed which changes the protein conformation so that the previously sequestered DNA-binding domain is free to bind DNA. Binds to sequences within in its own promoter when illuminated but not when it has been incubated in the dark.<ref>PMID:21606338</ref> | |||
