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) | ||||
Dgk | Diacylglycerol kinase 1; Upon cell stimulation converts the second messenger diacylglycerol into phosphatidate, initiating the resynthesis of phosphatidylinositols and attenuating protein kinase C activity (By similarity). May have a role in the development of the embryonic nervous system and the function of the adult nervous system and muscle; regulating signal transduction in neurons. (1230 aa) |
