Family

Membrane complex biogenesis protein, BtpA family (IPR005137)

Short name: BtpA

Overlapping homologous superfamilies

Family relationships

None.

Description

Members of this family are found in Caenorhabditis elegans, Synechocystis sp., E. coli, and several of the Archaea. Members in Cyanobacteria have been shown to play a role in protein complex biogenesis, and designated BtpA (biogenesis of thylakoid protein) [PMID: 9045660, PMID: 12651001]. BtpA appears to act at the level of Photosystem I (PSI) stabilisation [PMID: 10806238]. Homologues in non-photosynthetic species, where thylakoid intracytoplasmic membranes are lacking, are likely to act elsewhere in membrane protein biogenesis.
