InterPro domain: IPR039928

The LNK family consists of light and clock regulated morning genes from plants. These control both the pace of circadian rhythms and the photoperiodic regulation of flowering time by promoting the expression of a subset of clock and flowering time genes in the afternoon [ 1 ]. The LCL domain of clock-related factor REVEILLE8 recruits LNKs to target promoters, while its MYB domain provides DNA binding specificity. In turn, LNKs interact with RNA Polymerase II and the transcript elongation FACT complex, resulting in rhythmic changes of gene expression [ 2 ].
