CC   -!- FUNCTION: Probably plays a role in facilitating the assembly of
CC       multimeric protein complexes inside the ER. Is required for secretory
CC       polypeptide translocation. May physically associate with SEC63 protein
CC       in the endoplasmic reticulum and this interaction may be regulated by
CC       ATP hydrolysis. {ECO:0000250|UniProtKB:P16474}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + H2O = ADP + H(+) + phosphate; Xref=Rhea:RHEA:13065,
CC         ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,
CC         ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=3.6.4.10;
CC         Evidence={ECO:0000250|UniProtKB:P11021};
CC   -!- ACTIVITY REGULATION: The chaperone activity is regulated by ATP-induced
CC       allosteric coupling of the nucleotide-binding (NBD) and substrate-
CC       binding (SBD) domains. In the ADP-bound and nucleotide-free (apo)
CC       states, the two domains have little interaction. In contrast, in the
CC       ATP-bound state the two domains are tightly coupled, which results in
CC       drastically accelerated kinetics in both binding and release of
CC       polypeptide substrates. J domain-containing co-chaperones stimulate the
CC       ATPase activity and are required for efficient substrate recognition.
CC       {ECO:0000250|UniProtKB:P11021}.
CC   -!- SUBCELLULAR LOCATION: Endoplasmic reticulum lumen
CC       {ECO:0000250|UniProtKB:P16474, ECO:0000255|PROSITE-ProRule:PRU10138}.
CC   -!- INDUCTION: By heat shock and tunicamycin. Not induced by carbon source
CC       starvation. {ECO:0000269|PubMed:9370263}.
CC   -!- SIMILARITY: Belongs to the heat shock protein 70 family. {ECO:0000305}.
