| Locus name | AT5G01920.1 |
| Alias | STN8 |
| Organism | Arabidopsis thaliana |
| Taxonomic identifier | [NCBI] |
| Function category | kinase |
| Effect for Senescence | delay |
| Gene Description | 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. |
