UniProt annotation for STN8_ARATH » Serine/threonine-protein kinase STN8, chloroplastic
FUNCTION: Light-dependent serine/threonine protein kinase that specifically phosphorylates N-terminal threonine residues in psbA/D1, psbD/D2, psbC/CP43 and psbH, which are components of the core antenna complex of photosystem II. Phosphorylation of PSII core components facilitates the exchange of chlorophyll proteins between the grana and the stroma lamellae. Also involved in the phosphorylation of the calcium-sensing receptor (CaS).
