CC   -!- FUNCTION: Regulates a post-transcriptional process during the life
CC       cycle of the PSI protein complex such as (1) translation of the psaAB
CC       mRNA, (2) assembly of the PsaA/PsaB polypeptides and their associated
CC       cofactors into a functional complex, or (3) degradation of the protein
CC       complex.
CC   -!- SIMILARITY: Belongs to the BtpA family. {ECO:0000305}.
