UniProt functional annotation for Q9SSA5

UniProt code: Q9SSA5.

Organism: Arabidopsis thaliana (Mouse-ear cress).
Taxonomy: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliophyta; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis.
 
Function: Required for the assembly and stabilization of PSII, but has no PPIases activity.
 
Catalytic activity: Peptidylproline (omega=180) = peptidylproline (omega=0).
Subcellular location: Plastid, chloroplast thylakoid lumen.
Tissue specificity: Ubiquitous. Lower levels of expression in roots.
Induction: Up-regulated by light. Down-regulated by dark.
Domain: The N-teminal helical domain blocks the interaction with the potential target PSII subunit chlorophyll protein 47 (CP47).
Disruption phenotype: Stunted growth and hypersensitivity to high light.
Similarity: Contains 1 PPIase cyclophilin-type domain.
