Working day and night: plastid casein kinase 2 catalyses phosphorylation of proteins with diverse functions in light- and dark-adapted plastids.
Title: Working day and night: plastid casein kinase 2 catalyses phosphorylation of proteins with diverse functions in light- and dark-adapted plastids.
Chloroplast-targeted casein kinase 2 phosphorylates pTAC10.[chloroplast-targeted casein kinase 2]
Title: pTAC10, an S1-domain-containing component of the transcriptionally active chromosome complex, is essential for plastid gene expression in Arabidopsis thaliana and is phosphorylated by chloroplast-targeted casein kinase II.
Through functional characterization of two independent Casein kinase alpha4 RNAi lines the authors show that the fourth alpha subunit in Arabidopsis also functions redundantly in regulating ABA response, lateral root formation and flowering time.[CK2 alpha4]
Title: Arabidopsis casein kinase 2 α4 subunit regulates various developmental pathways in a functionally overlapping manner.
Plastid casein kinase 2 is an enhancing factor in abiotic stress signaling.
Title: Plastid casein kinase 2 knockout reduces abscisic acid (ABA) sensitivity, thermotolerance, and expression of ABA- and heat-stress-responsive nuclear genes.
Using bacterial overexpression of cpCK2, principal features of this enzyme are shown and functional determinants of its role as a transcriptional regulator in vitro has been assigned. Recombinant cpCK2 is capable of using various plant sigma transcription factors as phosphorylation substrates. [cpCK2]
Title: Phylogenetic and functional features of the plastid transcription kinase cpCK2 from Arabidopsis signify a role of cysteinyl SH-groups in regulatory phosphorylation of plastid sigma factors.
