CC -!- FUNCTION: Kinase that can phosphorylate the tocopherol cyclase VTE1, a
CC key enzyme of tocopherol (vitamin E) metabolism and involved in the
CC recycling of oxidated alpha-tocopherol quinone, possibly stabilizing it
CC at plastoglobules. Regulates also plastoglobule protein composition
CC (PubMed:24267661). Prevents photodamage of chloroplasts under
CC continuous red light, thus working in opposition to ABC1K3
CC (PubMed:25882344). Together with ABC1K1, contributes to plastoglobule
CC (PG) function in prenyl-lipid metabolism, stress response, and
CC thylakoid remodeling (PubMed:23673981, PubMed:24267661). Involved in
CC chlorophyll degradation and in the maintenance of the number of
CC chlorophyll-binding photosynthetic thylakoid membranes
CC (PubMed:22447966). Ensures photosynthetic electron transport by
CC regulating the homeostasis of plastoquinone, beta-carotene and
CC xanthophyll lutein, as well as membrane antioxidant tocopherol
CC metabolism (PubMed:24267661). Seems to affect specifically stability or
CC turnover of D1 protein, product of psbA, one of the four core subunits
CC of the photosystem II (PSII) (PubMed:25882344). Required for
CC photooxidative stress responses, including the induction of oxidative
CC stress response genes (e.g. FSD1, CSD1, CAT1, and UTG71C1), to prevent
CC photosystem II core and chlorophyll degradations (PubMed:22447966,
CC PubMed:23673981, PubMed:24267661). {ECO:0000269|PubMed:22447966,

CC -!- TISSUE SPECIFICITY: Expressed in all tissues (e.g. especially in
CC leaves) at all developmental stages from seed germination to flowering,
CC except in the root tips. {ECO:0000269|PubMed:22447966}.
CC -!- INDUCTION: Up-regulated by methyl viologen (paraquat, MV) treatment, a
CC herbicide triggering photooxidative stress.
CC {ECO:0000269|PubMed:22447966}.
CC -!- DISRUPTION PHENOTYPE: High chlorophyll fluorescence and reduced non-
CC photochemical quenching (NPQ) caused by defects in photosynthetic
CC electron transport. Specifically deficient in the electron carrier
CC plastoquinone, as well as in beta-carotene and the xanthophyll lutein,
CC and defective in membrane antioxidant tocopherol metabolism. Altered
CC plastoglobule protein composition (PubMed:24267661). Abnormal
CC development with albino cotyledons and paler mesophyll cells leading to
CC yellow-green leaves due to reduced contents of carotenoids and
CC chlorophyll, as well as changes in the numbers of chlorophyll-binding
CC proteins of the photosynthetic complexes (PubMed:22447966,
CC PubMed:24267661, PubMed:25882344). In bdr1-1 and bdr1-2, increased
CC accumulation of anthocyanin under red and blue light conditions.
CC Exposure to red light for 5 days leads to dwarf plants with pale green
CC rosette leaves. Reduced level of D1 protein, product of psbA, one of
CC the four core subunits of the photosystem II (PSII) (PubMed:25882344).
CC Increased levels of chlorophyll degradation products such as
CC chlorophyllide (Chlide) a and pheophorbide a. Stronger photosynthetic
CC and metabolic perturbations in response to high light stress and methyl
CC viologen (paraquat, MV), a herbicide triggering photooxidative stress,
CC strongly affecting carbohydrate metabolism (PubMed:22447966,
CC PubMed:24267661). However, the mutant acclimates to high light after 7
CC days together with a recovery of carotenoid levels and a drastic
CC alteration in the starch-to-sucrose ratio (PubMed:24267661). Lower
CC transcript levels of the oxidative stress response genes FSD1, CSD1,
CC CAT1, and UTG71C1 after MV treatment (PubMed:22447966). Conditional
CC light stress phenotype in the double mutant abc1k1 abc1k3 that displays
CC rapid chlorosis upon high light stress and slower, but irreversible,
CC senescence-like phenotype during moderate light stress, drought or
CC nitrogen limitation, but not cold stress. This senescence-like
CC phenotype is associated with the degradation of the photosystem II core
CC and up-regulation of chlorophyll degradation. Modified prenyl-lipid
CC composition in plastoglobules (PG) probably due to reduced VTE1
CC activity and loss of CCD4. Abnormal recruitment of plastid jasmonate
CC biosynthesis enzymes in PG (PubMed:23673981).
CC {ECO:0000269|PubMed:22447966, ECO:0000269|PubMed:23673981,
CC ECO:0000269|PubMed:24267661, ECO:0000269|PubMed:25882344}.
CC -!- SIMILARITY: Belongs to the protein kinase superfamily. ADCK protein
CC kinase family. {ECO:0000305}.
