Integration Of Local And Regional Regulatory Information In The Human Genome, Hemangi Govind Chaudhari

Arts & Sciences Electronic Theses and Dissertations

Gene regulation involves the integration of different sources of information at multiple levels. The action of transcription factors is integrated at cis-regulatory sequences (CRSs). Information from many CRSs is combined to drive spatiotemporally regulated gene expression. Prediction of CRS activity from DNA sequence is challenging because most occurrences of transcription factor binding sites (TFBS) are not functional. I assayed the activity of thousands of genomic sequences with Activator Protein 1 (AP-1) binding sites in K562 cells to identify features in flanking sequences that distinguish functional from non-functional TFBS. I find that sequence features directly adjacent to the AP-1 core motif, …
