Also known as
State transition 8; STATE TRANSITION 8; T20L15.190; T20L15_190
Summary
Chloroplast thylakoid protein kinase STN8 is specific in phosphorylation of N-terminal threonine residues in D1, D2 and CP43 proteins, and Thr-4 in PsbH protein of photosystem II. Phosphorylation of Thr-4 in the wild type required both light and prior phosphorylation at Thr-2.

What's a GeneRIF?
  1. analysis uncovers the STN7/STN8 kinases as mediators between photosynthetic electron transport, its immediate downstream sinks and long-term adaptation processes affecting metabolite accumulation and gene expression.
    Title: Identification of STN7/STN8 kinase targets reveals connections between electron transport, metabolism and gene expression.
  2. Data show that among several putative STN8 substrates, PGRL1-A is of particular importance because of its possible role in the modulation of cyclic electron transfer.

  4. In Arabidopsis a second protein kinase, STN8, is required for the quantitative phosphorylation of PSII core proteins; acclimation to changes in light quality is defective in stn7 but not in stn8 mutants [STN8]
