Su(var)3-3 | Possible lysine-specific histone demethylase 1; Probable histone demethylase that specifically demethylates 'Lys-4' of histone H3, a specific tag for epigenetic transcriptional activation, thereby acting as a corepressor. Required for heterochromatic gene silencing. Acts by oxidizing the substrate by FAD to generate the corresponding imine that is subsequently hydrolyzed. Demethylates both mono- and tri-methylated 'Lys-4' of histone H3. May also demethylate 'Lys-9' of histone H3, Plays a role in the repression of neuronal genes; Belongs to the flavin monoamine oxidase family. (890 aa) | ||||
Nca | Neurocalcin homolog; Calcium-binding protein that is essential for promoting night-time sleep and inhibiting nocturnal hyperactivity. During the night-time it promotes sleep by limiting synaptic output from arousal- and wake-promoting neurons within the C01- and A05- domains that include the mushroom body, and the antennal mechanosensory and motor center. Regulated by the circadian clock network and light- sensing circuits that include the CRY photoreceptor; it is likely that both of these internal and external cues are required to define the temporal window (the night-time) during whi [...] (190 aa) |
