| Locus name | AT5G64040 |
| Alias | PSAN |
| Organism | Arabidopsis thaliana |
| Taxonomic identifier | [NCBI] |
| Function category | light signaling |
| Effect for Senescence | delay |
| Gene Description | Encodes the only subunit of photosystem I located entirely in the thylakoid lumen. May be involved in the interaction between plastocyanin and the photosystem I complex. Phosphorylation of this protein is dependent on calcium. |
| Evidence | Genetic evidence:Mutant [Ref 1] |
