WebApr 11, 2024 · FAD deficiency affected CRY stability and accumulation in the circadian cycle (Figure 1 and and4C), 4C), suggesting that FAD-mediated stabilization contributes to the nuclear accumulation of CRY. We also found that RFK protein levels (the rate-limiting FAD biosynthetic enzyme) in the nucleus show circadian changes ( Figure 2B ).

WebCryptochromes (CRYs) are a group of blue and UV-A photoreceptors that are present across all major lineages. Biochemically these are flavoproteins that regulate a number of growth and developmental processes in response to light irradiance (Pedmale et al., 2016 ). WebApr 5, 2024 · A plant-like cryptochrome of diatom microalgae, CryP, acts as a photoreceptor involved in transcriptional regulation. It contains FAD and 5,10-methenyltetrahydrofolate as chromophores. Here, we demonstrate that the unstructured C-terminal extension (CTE) of CryP has an influence on the redox state o …
