  • 功能：
    Functions as a co-chaperone, regulating the substrate binding and activating the ATPase activity of chaperones of the HSP70/heat shock protein 70 family. In parallel, also contributes to the ubiquitin-dependent proteasomal degradation of misfolded proteins. Thereby, may regulate the aggregation and promote the functional recovery of misfolded proteins like HTT, MC4R, PRKN, RHO and SOD1 and be crucial for many biological processes. Isoform 1 which is localized to the endoplasmic reticulum membranes may specifically function in ER-associated protein degradation of misfolded proteins.

    1. Study describes the identi fi cation of the fi rst deletion reported at the DNAJB2 locus, further expanding its phenotypic and genotypic spectrums as well as its disease-associated mechanisms with spinal muscular atrophy and parkinsonism. PMID: 27449489
    2. Our results disclose a novel interplay between ubiquitin- and phosphorylation-dependent signalling, and represent the first report of a regulatory mechanism for UIM-dependent function. They also suggest that CK2 inhibitors could release the full neuroprotective potential of HSJ1, and deserve future interest as therapeutic strategies for neurodegenerative disease. PMID: 28031292
    3. The results of this study confirm that HSJ1 mutations are a rare but detectable cause of autosomal recessive dHMN and CMT2. PMID: 25274842
    4. HSJ1a acts on mutant SOD1 through a combination of chaperone, co-chaperone and pro-ubiquitylation activity. PMID: 24023695
    5. a mutation causing a loss-of-function of HSJ1 is linked to a pure lower motor neuron disease, strongly suggesting that HSJ1 also plays an important and specific role in motor neurons. PMID: 22522442
    6. Data show that DNAJB2 is expressed in skeletal muscle at the neuromuscular junction of normal fibers, in the cytoplasm and membrane of regenerating fibers, and in protein aggregates and vacuoles in protein aggregate myopathies. PMID: 20395441
    7. data provide evidence that cytoplasmic chaperones HSJ1a and HSJ1b when targeted to the endoplasmic reticulum can influence the folding and processing of rhodopsin PMID: 12754272
    8. HSJ1 is a neuronal shuttling factor for the sorting of chaperone clients to the proteasome. PMID: 15936278
    9. Cystamine and cysteamine increase brain levels of BDNF in Huntington disease via HSJ1b and transglutaminase PMID: 16604191
    10. Damaging exercise induced the expression of capZalpha, MCIP1, CARP1, DNAJB2, c-myc, and junD, each of which are likely involved in skeletal muscle growth, remodeling, and stress management. PMID: 18321953
