Protein
Tetratricopeptide repeat domain-containing protein PYG7, chloroplastic
Organism
Arabidopsis thaliana
Function
Nuclear genome-encoded factor required for the accumulation of photosystem I (PSI). Functions as PSI biogenesis factor (PubMed:16679416, PubMed:28522455). Cooperates with PSA3 to promote the stable assembly of PSI in the thylakoid membrane. May target primarily the PsaC subunit (PubMed:28522455).
