靶點詳情

5. STIP1 modulates the function of the HSP90-JAK2-STAT3 complex PMID: 27409672
6. Hsp70/Hsp90-organizing protein promoter activity was highest in Hs578T which expressed mutant or inactive p53. HRAS activation of the Hsp70/Hsp90-organizing protein promoter was inhibited by p53 overexpression. PMID: 27987076

9. Data suggest that calcium signaling plays important role in prevention of protein misfolding; complexes of S100A1 and STIP1 are key players in this pathway; the stoichiometry of S100A1/STIP1 interaction appears to be three S100A1 dimers plus one STIP1 monomer; each S100A1-STIP1-binding interaction is entropically driven. (S100A1 = S100 calcium binding protein A1; STIP1 = stress-induced-phosphoprotein 1) [REVIEW] PMID: 28819010
10. Results indicte the great potential of STIP1 (stress-induced phosphoprotein 1) as a biomarker and therapeutic target in renal cell carcinoma (RCC) bone metastasis. PMID: 28199984
11. Data suggest that three dimers of S100A1 (S100 calcium binding protein A1) associate with one molecule of STIP1 (stress-inducible phosphoprotein 1) in a calcium-dependent manner; individual STIP1 TPR (tetratricopeptide repeat) domains, TPR1, TPR2A and TPR2B, bind a single S100A1 dimer with significantly different affinities; TPR2B domain possesses highest affinity for S100A1. PMID: 28408431
12. Data confirmed the significant up-regulation of STIP1 in tumorous cholangiocytes relative to normal hepatocytes and non-tumorous cells and show prooved it as a reliable diagnostic biomarker when using immunohistochemistry. PMID: 25034945

16. our findings provide evidences that positive expression of STIP1 in papillary thyroid carcinoma may be important in the acquisition of an aggressive phenotype PMID: 24163084

23. STIP-1 is an antigenic target in cultured hippocampal neurons in sera and/or cerebrospinal fluids of patients with neuro-Behcet's disease. PMID: 21875754
24. We found no genome-wide statistically significant associations but identified several plausible candidate genes among findings at p < 5E-05: STIP1, TMEM132D, LRRC7, SEMA3A, and ALK. PMID: 21784300
25. High STIP1 is associated with pancreatic Cancer. PMID: 21470770
26. This study has revealed that Rho GDP-dissociation inhibitor 2, Y-box binding protein 1, and the HSP70/90 organizing protein have a critical role to play in resistance to cyclin-depedent kinases inhibitor. PMID: 21067243
27. show that stress-induced phosphoprotein 1 (STIP1) was secreted by ovarian cancer tissues into the peripheral blood of patients, resulting in a significant increase of serum levels of STIP1 in cancer patients compared with those in normal controls PMID: 20501939
28. Presented: Hop-D456G, a Hop mutant within the TPR2B-domain, that is a mixture of monomeric and dimeric species, suggesting the TPR2B-domain may also play a role in dimerization. PMID: 19961430
29. Sedimentation equilibrium AUC clearly shows that HOP is a monomer, with no indication of higher MW species. An in vivo coexpression assay that also supports the conclusion that HOP is a monomer. PMID: 19866486

33. It is likely that Hop binds to both monomers of Hsp90 in the form of a clamp, interacting with residues in the middle domain of Hsp90, preventing ATP hydrolysis, possibly by the preventing binding of N-terminal and middle domains in Hsp90 monomers. PMID: 18485364
