General Information

Term

protein translocation chaperone activity

ID (Ontology)

GO:0140388 (Gene Ontology)

Definition

Binding to the exposed unfolded portion of a polypeptide as it emerges from a membrane translocation channel/pore to drive its unidirectional transport across a membrane. Iterative cycles of ATP-dependent binding/rebinding by the chaperone prevents back sliding and drive vectorial transport.[ PubMed:11733493 ]
