Function

PHOT_CHLRE Protein kinase that acts as a blue light photoreceptor (PubMed:15695460, PubMed:24285544). Required for non-photochemical quenching (NPQ), a mechanism that converts and dissipates the harmful excess absorbed light energy into heat and protect the photosynthetic apparatus from photo-oxidative damage (PubMed:27626383). Controls the energy-dependent chlorophyll fluorescence quenching (qE) activity of chlorophyll excited states by inducing the expression of the qE effector protein LHCSR3 in high light intensities (PubMed:27626383).[1] [2] [3]
