PSA3

Gene
PSA3
Protein
Photosystem I assembly factor PSA3, chloroplastic
Organism
Arabidopsis thaliana
Length
277 amino acids
Function
Nuclear genome-encoded factor required for the accumulation of photosystem I (PSI). Functions as PSI biogenesis factor. Cooperates with PYG7 to promote the stable assembly of PSI in the thylakoid membrane. May target primarily the PsaC subunit. Does not seem to be required for the expression of chloroplast genes encoding PSI subunits.
