The RING-finger domain of the fungal repressor crgA is essential for accurate light regulation of carotenogenesis.

Abstract excerpt

Mucor circinelloides responds to blue light by activating the biosynthesis of carotenoids. Gene crgA acts as a repressor of this light-regulated process, as its inactivation leads to overaccumulation of carotenoids in both the dark and the light. The predicted CrgA protein contains different recognizable structural domains, including a RING-finger zinc-binding motif, several glutamine-rich regions, a putative...
