CC   -!- FUNCTION: Co-chaperone for Hsp70 protein HSPA5/BiP that acts as a key
CC       repressor of the ERN1/IRE1-mediated unfolded protein response (UPR) (By
CC       similarity). J domain-containing co-chaperones stimulate the ATPase
CC       activity of Hsp70 proteins and are required for efficient substrate
CC       recognition by Hsp70 proteins (PubMed:11836248). In the unstressed
CC       endoplasmic reticulum, interacts with the luminal region of ERN1/IRE1
CC       and selectively recruits HSPA5/BiP: HSPA5/BiP disrupts the dimerization
CC       of the active ERN1/IRE1 luminal region, thereby inactivating ERN1/IRE1
CC       (By similarity). Also involved in endoplasmic reticulum-associated
CC       degradation (ERAD) of misfolded proteins (PubMed:22267725). Required
CC       for survival of B-cell progenitors and normal antibody production
CC       (PubMed:25222125). {ECO:0000250|UniProtKB:G3H0N9,

CC       ECO:0000269|PubMed:25222125}.
CC   -!- SUBUNIT: Interacts with HSPA5/BiP; interaction is direct
CC       (PubMed:11836248). Interacts with ERN1/IRE1 (via the luminal region)
CC       (By similarity). Interacts with DERL1 (PubMed:22267725).

CC       ECO:0000269|PubMed:22267725}.
CC   -!- SUBCELLULAR LOCATION: Endoplasmic reticulum lumen
CC       {ECO:0000269|PubMed:22267725, ECO:0000305|PubMed:11836248}.
CC   -!- DOMAIN: The J domain stimulates the ATPase activity of HSPA5/BiP, while
CC       the divergent targeting domain is required for efficient substrate
CC       recognition by HSPA5/BiP. The divergent targeting domain specifically
CC       recognizes and binds to aggregation-prone sequences.
CC       {ECO:0000269|PubMed:27546788}.
CC   -!- PTM: Not N-glycosylated. {ECO:0000269|PubMed:11836248}.
CC   -!- DISRUPTION PHENOTYPE: Perinatal death in approximately half of knockout
CC       mice (PubMed:24336520). Death is caused by fetal growth restriction,
CC       reduced hepatic glycogen stores and hypoglycemia (PubMed:24336520).
CC       Surviving adult mice display constitutive endoplasmic reticulum stress
CC       in multiple cells and tissues (PubMed:24336520). Elevated endoplasmic
CC       reticulum stress in pancreatic beta cells is associated with beta cell
CC       loss, hypoinsulinemia and glucose intolerance (PubMed:24336520)
CC       Conditional knockout mice lacking Dnajb9 in bone marrow show impaired
CC       hematopoiesis: the number of myeloid cells is increased, while the
CC       number of erythroid and B lymphoid cells is reduced (PubMed:25222125).
CC       B-cell defects cause decreased survival of B-cell precursors, including
CC       large and small pre-B, and immature B-cells (PubMed:25222125).
CC       {ECO:0000269|PubMed:24336520, ECO:0000269|PubMed:25222125}.
CC   -!- CAUTION: Was initially thought to be an integral membrane protein
CC       (PubMed:11836248). However, it was later shown that it is a soluble
CC       luminal protein localized in the endoplasmic reticulum lumen.
