Summary: DNAJB12 belongs to the evolutionarily conserved DNAJ/HSP40 family of proteins, which regulate molecular chaperone activity by stimulating ATPase activity. DNAJ proteins may have up to 3 distinct domains: a conserved 70-amino acid J domain, usually at the N terminus; a glycine/phenylalanine (G/F)-rich region; and a cysteine-rich domain containing 4 motifs resembling a zinc finger domain (Ohtsuka and Hata, 2000 [PubMed 11147971]).[supplied by OMIM, Mar 2008]
Expression: Ubiquitous expression in testis (RPKM 9.5), kidney (RPKM 9.2) and 25 other tissues See more

DNAJB12 and DNJB14 are non-redundant Hsp40 redox chaperones involved in endoplasmic reticulum protein reflux.
Title: DNAJB12 and DNJB14 are non-redundant Hsp40 redox chaperones involved in endoplasmic reticulum protein reflux.
ER-located J-protein chaperones were identified as key regulators for the iogenesis and physiological function of ERG K+ channels. They regulate two distinct aspects of K+ channel biogenesis, the stabilization and assembly of channel subunits.
Title: Tetrameric Assembly of K(+) Channels Requires ER-Located Chaperone Proteins.
Data suggest that endoplasmic reticulum (ER) stress-induced apoptosis in hepatoma cells is regulated by highly labile and ER-associated BCL-2 family member BOK, which is controlled at level of protein stability by ER-associated degradation components; DNAJB12 is required in hepatoma cells to maintain BOK at low levels and suppress ER stress. (DNAJB12 = DnaJ (Hsp40) homolog, subfamily B, member 12)
Title: Endoplasmic reticulum stress-induced degradation of DNAJB12 stimulates BOK accumulation and primes cancer cells for apoptosis.
Over-expression of DNAJB12 or DNAJB14 causes the formation of elaborate membranous structures within cell nuclei, designated DJANGOS for DNAJ-associated nuclear globular structures.
Title: Expression of DNAJB12 or DNAJB14 causes coordinate invasion of the nucleus by membranes associated with a novel nuclear pore structure.
JB12 cooperates with cytosolic Hsc70 and the ubiquitin ligase RMA1 to target CFTR and CFTRDeltaF508 for degradation.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
