靶點詳情

功能：

This is an intracellular thiol proteinase inhibitor. Tightly binding reversible inhibitor of cathepsins L, H and B.
基因功能參考文獻：
1. cystatin B expression was significantly and inversely correlated with lung tumor stage and tumor grade PMID: 29037838
2. The results demonstrate that cystatin B interferes with the STAT-1 signaling and IFN-beta-antiviral responses perpetuating HIV in macrophage reservoirs. PMID: 27137788
3. apoptosis is accompanied by degradation of the cysteine cathepsin inhibitor stefin B (StfB). CatD did not exhibit a crucial role in this step. However, this degradation was partially prevented through pre-incubation with the antioxidant N-acetyl cysteine PMID: 28543404
4. Homozygous for a c.218dupT (p.His75Serfs*2) mutation in exon 3 of CSTB causes neurodegeneration, progressive cerebral volume loss and diffuse hypomyelination. PMID: 28378817

6. It was shown that decreased expression of cystatin B enhances cathepsin activity in Niemann-Pick C cerebellar degeneration patient fibroblasts. PMID: 26908626
7. High expression of stefin B may be an important factor contributing to the development and metastasis of Hepatocellular Carcinoma. PMID: 26753874
8. CSTB null mutation associated with microcephaly, early developmental delay, and severe dyskinesia. PMID: 26843564
9. Data shows that CYTB and ANXA4 overexpression may be involved in carcinogenesis and histopathological differentiation of ovarian clear cell carcinoma and suggest they may serve as a potential diagnostic biomarkers. PMID: 25633807
10. A role for disease-causing mutations in cystatin B gene in patients with juvenile myoclonic epilepsy was not supported. PMID: 25752200
11. Even though the majority of EPM1 patients have a uniform genetic mutation, the actual size of the longer CSTB expansion mutation allele is likely to have a modulating effect on the age at disease onset, myoclonus severity, and cortical neurophysiology. PMID: 25770194
12. The study shows detection of stefin B dimers in HEK293 cells and the importance of their residual activity. PMID: 25047918
13. glutamate dehydrogenase is a euchromatin-associated enzyme, and its H3 clipping activity is regulated by chromatin structure, histone modifications and an in vivo inhibitor. PMID: 25263734
14. detected a homozygous expansion of dodecamer repeats in the CSTB gene in four patients with clinical diagnosis of ULD. PMID: 23883076
15. The increased CSTB expression in ovarian tissue represents tumor progression and is dysregulated by the TGF-beta signaling pathway. PMID: 24452274
16. A reciprocal influence of CSTB and SOD1 at the gene expression level and for a direct interaction of the two proteins, is reported. PMID: 24234043
17. The present study was performed on two more missense mutants of human stefin B, G50E and Q71P, and they similarly showed numerous aggregates upon overexpression. PMID: 24909779
18. The co-localization of stefin B wild type and EPM1 mutants with cathepsins showed that cathepsins accumulate around the aggregates formed by the EPM1 mutants. PMID: 23362198
19. Skull thickening and an increased prevalence of abnormal findings in skeletal radiographs of patients with EPM1 suggest that this condition is connected to defective cystatin B function. PMID: 23010349
20. This study suggested that CSTB mutations other than the common dodecamer expansion predict particular phenotypes, including marked seizure severity and polymorphous seizure types. PMID: 23205931
21. Elevated StefA mRNA level is associated with invasive glioblastoma. PMID: 22287159
22. S-glutathionylation and S-cysteinylation were described as extensive PTM of a salivary protein and the first time that these PTMs were detected in naturally occurring cystatin B. PMID: 22057043
23. patients compound heterozygous for the dodecamer repeat expansion and the c.202C>T mutations seem to have a severer form of Unverricht-Lundborg disease (EPM1) than patients homozygous for the expansion mutation PMID: 21757863
24. At pH 7.0 the mutant H75W folded in three kinetic phases to a native-like intermediate, analogous to folding of stefin B at pH 4.8. PMID: 22033403
25. Intracellular stefin b aggregation shows a negative correlation with cell survival PMID: 20078424

27. oligomers of stefin B and amyloid-beta interact in vitro and in cells PMID: 19955183
28. Oligonucleotides containing EPM1 repeat adopt secondary structures that may facilitate strand slippage thereby causing the expansion. PMID: 11697734

30. analysed eight markers flanking CSTB(GT10-D21S1890-D21S1885-D21S2040-D21S1259- CSTB-D21S1912-PFKL-D21S171) and one intragenic variant in the CSTB 3' UTR (A2575G) PMID: 12215838
31. first demonstration of cysteine protease activity being regulated by CSTB activity in a biological context; effects of decreased CSTB activity in EPM1 pathogenesis may be mediated by cathepsins through increased activity of cathepsins S and L PMID: 12452481
32. Prefibrillar oligomers/aggregates of stefin B also increase the surface pressure at an air-water interface, i.e. they have amphipathic character and are surface seeking. PMID: 15955063
33. These data show that cystatin B inhibits bone resorption by down-regulating intracellular cathepsin K activity despite increased osteoclast survival. PMID: 16321512
34. Study shows that copper binding by stefin B inhibits the amyloid fibril formation and, to a lesser degree, the initial aggregation. PMID: 16939620
35. Several alternatively spliced CSTB isoforms were identified in patients with progressive myoclonus epilepsy of Unverricht-Lundborg type . PMID: 17003839
36. Results describe the influence of pH and trifluoroethanol on amyloid fibril growth and morphology from human stefin B. PMID: 17701471
37. cystatin B in vivo has a polymeric structure sensitive to the redox environment and that overexpression of the protein generates aggregates. PMID: 17920138
38. CSTB is specifically overexpressed in most HCCs and is also elevated in the serum of a large proportion of HCC patients PMID: 18281540
39. Data show that wild-type stefin B and its Y31 isoform are able to form pores in planar lipid bilayers, whereas the G4R isoform destroys the bilayer by a non pore-forming process. PMID: 18397316
