UniProtKB description:  Chaperone that functions as a gatekeeper on the periplasmic side of the SecYEG translocon (PubMed:18439025, PubMed:20920237, PubMed:29097228). Facilitates the translocation of precursor proteins across SecYEG by interacting with the translocating substrate (PubMed:29097228). Also plays a role in the release of newly synthesized secreted proteins at the periplasmic exit site of the Sec translocon (PubMed:18439025, PubMed:20920237, PubMed:29097228). May be involved in the early periplasmic folding of many newly translocated proteins (PubMed:18439025, PubMed:20920237). Acts as a transient subunit of the Sec translocon that binds to the lateral gate of SecY and is detached by nascent membrane proteins but not by SecA (PubMed:24951590).
