Investigating The Role Of The Nucleosome Remodeling Factor Nurf As A Regulator Of Gene Expression, Aiman S. Alhazmi
Theses and Dissertations
The nucleosome remodeling factor (NURF) is an evolutionary conserved ATP-dependent chromatin remodeling factor. It was first isolated from Drosophila as a complex with enzymatic activity that once recruited to nucleosome, it slides the nucleosome to provide accessibility for transcription factors. Since then, numerous works from animal models and cell lines show the role of NURF as a regulator of gene expression. NURF interacts with H3K4me3 and sequence specific transcription factors that recruit the complex to promoter regions. Whether this is the only mechanism by which NURF regulates gene expression is not known. However, other ATP-dependent chromatin remodeling complexes are known …

Theses and Dissertations
The nucleosome remodeling factor (NURF) is a mutli-protein complex that plays a role in the regulation of gene expression through its ability to remodel nucleosomes. The largest subunit of this complex, Bptf (Bromodomain PHD Finger Transcription Factor) is important for many cellular processes as a transcriptional regulator and improper function results in disease or malignancy. To further understand the genome-wide recruitment of the NURF complex, the interaction partner for the N-terminal PHD finger domain of Bptf was investigated through pull down assays followed by mass spectrometry. It was determined that this domain does not recognize histones; instead it recognizes a …
