1. TP53INP2 promotes ribosome biogenesis through facilitating rRNA synthesis at the nucleolus PMID: 27172002
2. Study demonstrated that HMG box 1, the linker region between the HMG boxes and C-terminal acidic region (AR), and the AR cooperatively regulate the nucleolar localization of UBF. PMID: 28874518
3. In seven unrelated affected individuals, all suffering from developmental regression starting at 2.5-7 years, the s identified a heterozygous variant, c.628G>A in UBTF, encoding p.Glu210Lys in UBF, which occurred de novo in all cases. PMID: 28777933
4. RINT-1 interacts with MSP58 and UBF within nucleoli and plays a role in ribosomal gene transcription. PMID: 27530925
5. This study provides some compelling evidences in support of HBx-elicited and c-Myc-mediated increase in UBF levels that abets oncogenic onslaught in hepatic cells by increasing rDNA transcription and ribosome biogenesis. PMID: 25890091
6. These results suggest that UBF can inhibit gene expression from viral DNA prior to its replication. PMID: 25965800
7. we have uncovered a novel role for UBTF1 and UBTF2 in maintaining genome stability through coordinating the expression of highly transcribed Pol I (UBTF1 activity) and Pol II genes (UBTF2 activity). PMID: 25452314
8. p14ARF fails to prevent E7-mediated UBF1 phosphorylation, but could facilitate nucleolar pRb inactivation by targeting E7 to the nucleolus. PMID: 24798431
9. PIP2 depletion reduces Pol I transcription. PMID: 23591814
10. UBF is expressed widely by human multiple fetal tissue,s and the expression level is very high in HL-60 cells. PMID: 21162312
11. Downregulation of RUNX2 expression reduces the localization of HDAC1 to the nucleolar periphery and also decreases the association between HDAC1 and UBF. PMID: 22393235
12. hALP binds the upstream binding factor (UBF) in vivo and in vitro PMID: 21177859
13. depletion of upstream binding factor (UBF; an rRNA transcription factor) decreased the chromatin binding affinity of B23, which in turn led to an increase in histone density at the r-chromatin PMID: 20713446
14. The three-dimensional solution structure of the first high mobility group (HMG) box domain in upstream binding factor has been determined by multidimensional NMR. PMID: 11969401
15. we have identified an interaction between UBF and TAF1, a factor involved in the transcription of cell cycle and growth regulatory genes. Coimmunoprecipitation and protein-protein interaction assays confirmed that TAF1 binds to UBF. PMID: 12498690
16. The DNA binding affinity of UBF's fifth box domain (HMG box 5) is found to be much weaker than that of the first HMG box domain (HMG box 1). PMID: 12590579
17. Data show that both UBF1 and UBF2 activate RNA polymerase II-regulated, beta-catenin-responsive promoters. PMID: 12748295
18. Proto-Oncogene Proteins c-myc activated transcription from the UBF promoter PMID: 15282543
19. results suggest that extensive binding of UBF is responsible for formation and maintenance of the secondary constriction at active NORs, and that UBF mediates recruitment of the pol I machinery to nucleoli independently of promoter elements PMID: 15598984
20. Data suggest that the A state of human upstream binding factor HMG Box1 could represent a potential folding intermediate on protein folding pathway. PMID: 15752694
21. A potential protein-folding pathway is proposed for upstream binding factor HMG box 1 domain based on the early stages of its pH 2.1 unfolded state characterized by multidimensional heteronuclear magnetic resonance spectroscopy. PMID: 15924431
22. SL1 directs preinitiation complex formation, functioning in core promoter binding, RNA polymerase I recruitment, and UBF stabilization. PMID: 15970593
23. model for CAST/hPAF49 function in which the network of interactions of Pol I-specific subunits with UBF facilitates conformational changes of the polymerase, leading to stabilization of the Pol I-template complex and, thereby, activation of transcription PMID: 16809778
24. UBF activates transcription in the transition between initiation and elongation, at promoter escape by RNA polymerase I (Pol I). PMID: 16858408
25. Upon p14ARF overexpression, UBF was found hypophosphorylated, thus unable to efficiently recruit the transcription complex, these data define a new p53-independent pathway that could regulate cell cycle through the negative control of rRNA transcription. PMID: 16924243
26. GdmCl-induced equilibrium unfolding transition of HMG box 5 of hUBF was monitored by both circular dichroism and fluorescence spectra. A cooperative two-state unfolding process was observed PMID: 17260958
27. possible sites in hUBF HMG box 5 that may interact with the first bromodomain of TAF1 were proposed PMID: 17505112
28. transcription factor UBF binds extensively across rDNA throughout the cell cycle, resulting in a specialized form of chromatin that is the hallmark of active nucleolar organizer regions PMID: 17699751
29. found a small but significant difference between the emerging daughter cells in the number of UBF-loaded NORs PMID: 18502146
30. The s propose that UBF is recruited to the replication compartments to aid replication of HSV-1 DNA. PMID: 19088274
31. The established differential localization of UBF in nucleoli of HeLa cells has a functional meaning. It reflects both the level of rRNA synthesis activities and the architectural role of UBF in nucleoli of these cells. PMID: 19393134
32. these results implicate a fluid helix-turn-helix folding model of hUBF Box-5. PMID: 19452555
33. central repeated domain of treacle binds with RNA polymerase I, while that the treacle C-terminus is involved in rDNA promoter recognition and UBF recruitment. PMID: 19527688
