- UBF is expressed widely by human multiple fetal tissue,s and the expression level is very high in HL-60 cells. PMID: 21162312

- hALP binds the upstream binding factor (UBF) in vivo and in vitro PMID: 21177859
- 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

- Proto-Oncogene Proteins c-myc activated transcription from the UBF promoter PMID: 15282543

- UBF activates transcription in the transition between initiation and elongation, at promoter escape by RNA polymerase I (Pol I). PMID: 16858408
- 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
