RT "PSA3, a protein on the stromal face of the thylakoid membrane, promotes
RT photosystem I accumulation in cooperation with the assembly factor PYG7.";
RL Plant Physiol. 174:1850-1862(2017).
CC -!- FUNCTION: Nuclear genome-encoded factor required for the accumulation
CC of photosystem I (PSI). Functions as PSI biogenesis factor. Cooperates
CC with PYG7 to promote the stable assembly of PSI in the thylakoid
CC membrane. May target primarily the PsaC subunit. Does not seem to be
CC required for the expression of chloroplast genes encoding PSI subunits.
CC {ECO:0000269|PubMed:28522455}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC {ECO:0000269|PubMed:28522455}; Peripheral membrane protein
CC {ECO:0000269|PubMed:28522455}. Note=Associates with the stromal face of
CC the thylakoid membrane. {ECO:0000269|PubMed:28522455}.
CC -!- DISRUPTION PHENOTYPE: Pale green phenotype.
