Phospho-HSPB6 (S16) Antibody

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
11. HSP20 directly associates with PI3K subunits and suppresses its activity in hepatocellular carcinoma, resulting in the inhibition of the AKT pathway, and subsequently decreasing the growth of hepatocellular carcinoma. PMID: 24223153
12. 14-3-3zeta and possibly other 14-3-3 isoforms may have additional functional roles conducted by the monomeric state PMID: 22794279
13. the cytosolic protein AKAP-Lbc (AKAP13) as the anchoring protein responsible for directing PKA phosphorylation of Hsp20 on Ser(16) PMID: 22731613
14. Hsp20 serves as a novel cardiokine in regulating myocardial angiogenesis through activation of the VEGFR signaling cascade. PMID: 22427880
15. cofilins 1 and 2 only weakly interact with 14-3-3 and therefore cannot directly compete with phosphorylated small heat shock protein HspB6 for its binding to 14-3-3 PMID: 22450169
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
17. A potential molecular mechanism by which Hsp20 acetylation can affect myometrial activity by liberating cofilin PMID: 21803775
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
19. Nevertheless, in solution, both alpha-crystallin domain proteins form stable dimers via the symmetric antiparallel interaction of beta7 strands. PMID: 21641913
20. The 14-3-3 zeta mutation mimicking phosphorylation of Ser184 does not markedly affect interaction with tau protein and improves the interaction of 14-3-3 zeta with HspB6. PMID: 21081103
21. Data show that the interaction between HspB6 and Bag3 requires the same regions that are involved in the HspB8-Bag3 association. PMID: 19845507
22. Our results suggest that a variety of oligomers composed of different proportions of different sHSPs may form in cell types expressing multiple sHSPs. PMID: 16225851
23. Phosphorylation led to changes in actin cytoskeletal morphology in 3T3 cells, delineating strategies for the expression and activation of therapeutic molecules for intracellular protein based therapeutics. PMID: 17084643
24. Interaction of human 14-3-3gamma with the small heat shock protein Hsp20 was analyzed by means of size-exclusion chromatography and chemical crosslinking. PMID: 17109079
25. Data support a novel role for pHSP20 in the modulation of cyclic-nucleotide-mediated myometrial relaxation, through interaction with actin. pHSP20 represents an important new target for future tocolytic therapy. PMID: 18755793
26. AZX100, an analogue of the small heat shock protein, HSP20, reduces TGF-beta1-induced CTGF expression in keloid fibroblasts PMID: 18787533
27. Human mutation in the anti-apoptotic heat shock protein 20 abrogates its cardioprotective effects PMID: 18790732
28. Here, crystal structures of excised alpha-crystallin domain from rat Hsp20 and that from human alphaB-crystallin show that they form homodimers with a shared groove at the interface by extending a beta sheet. PMID: 19646995
29. Report increased levels of phosphorylated Hsp20 in failing hearts. PMID: 19850943
