靶点详情

  • 功能：
    Small heat shock protein which functions as a molecular chaperone probably maintaining denatured proteins in a folding-competent state. Seems to have versatile functions in various biological processes. Plays a role in regulating muscle function such as smooth muscle vasorelaxation and cardiac myocyte contractility. May regulate myocardial angiogenesis implicating KDR. Overexpression mediates cardioprotection and angiogenesis after induced damage. Stabilizes monomeric YWHAZ thereby supporting YWHAZ chaperone-like activity.

    1. Structural basis for the interaction of a human HSPB6 protein with the 14-3-3 universal signaling regulator has been reported. PMID: 28089448
    2. Data suggest that HSPB6 forms hetero-oligomers with HSPB1 under the following rules: (1) highly conserved motif RLFDQXFG is necessary for subunit exchange among oligomers, (2) a site about 20 residues downstream of this motif determines size of resultant hetero-oligomers, and (3) a region in the N-terminal domain that is unique to HSPB6 dictates preferential formation of heterodimers. (HSP = heat shock protein) PMID: 28487364
    3. findings strongly suggest that phosphorylated HSP20 inhibits TGF-alpha-induced HCC cell migration and invasion via suppression of the JNK signaling pathway PMID: 27046040
    4. multiple sclerosis lesions revealed exclusive induction of HSPB6 in astrocytes, as confirmed by co-localization of HSPB6 with GFAP. PMID: 26694816
    5. N-terminal mutations increase stability of large HspB1 homooligomers, prevent their phosphorylation-dependent dissociation, modulate their interaction with HspB6 and decrease their chaperoning capacity, preventing normal functioning of HspB1. PMID: 25965061
    6. Findings strongly suggest that HSP20 directly associates with Bax and stimulates caspase cascade in human hepatocellular carcinoma cells. PMID: 24969689
    7. Data suggest that heat shock protein 20 (HSP20) may have value as a prognostic tumor marker and its overexpression might be a novel strategy for colorectal cancer (CRC) therapy. PMID: 25187324
    8. peptides in heat-shock protein Hsp20 (G71HFSVLLDVKHFSPEEIAVK91) and Hsp27 (D93RWRVSLDVNHFAPDELTVK113) with sequence homology to alpha-crystallin also have robust chaperone and anti-apoptotic activities. PMID: 25332102
    9. These findings strongly suggest that HSP20 might decrease the IKK-alpha protein level and that it down-regulates the TNF-alpha-stimulated intracellular signaling in HCC, thus resulting in the suppression of HCC progression. PMID: 25447820
    10. HSP20 may play a protective role against the progression of ovarian cancer. PMID: 25423708

    16. Properties of the monomeric form of 14-3-3zeta protein and its interaction with tau and HspB6. This interaction requires phosphorylation of tau protein and HspB6. PMID: 21978388

    18. Overexpression of HSPB1, as well as HSPB6, HSPB7 and HSPB8 independently protect against tachycardia remodeling by attenuation of the RhoA GTPase pathway at different levels. PMID: 21731611

    21. Data show that the interaction between HspB6 and Bag3 requires the same regions that are involved in the HspB8-Bag3 association. PMID: 19845507
