BtpA/SgcQ family protein similar to Synechocystis sp. photosystem I biogenesis protein BtpA that regulates a post-transcriptional process during the life cycle of the PSI protein complex such as, translation of the psaAB mRNA, assembly of the PsaA/PsaB polypeptides and their associated cofactors into a functional complex, and degradation of the protein complex

Members of this family are found broadly, incuding Synechocystis sp. (BtpA), E. coli (SgcQ/YjhM), several of the Archaea, and the model round worm, C. elegans. Members in Cyanobacteria have been shown to play a role in protein complex biogenesis, and designated BtpA (biogenesis of thylakoid proteins A). Functions in non-photosynthetic species, where thylakoid intracytoplasmic membranes are lacking, are unknown, but a role in biogenesis of membrane protein complexes is possible.
