Active Motif's Podcast

In this episode of the Epigenetics Podcast, we talked with Sven Heinz from the University of California in San Diego about his work on the impact of sequence variation on transcription factor binding affinities and genetic diversity. Sven Heinz talks about a landmark study published in Nature that examined the impact of sequence variation on transcription factor binding affinities and downstream effects on gene expression. Modifying genetic sequences to understand the influence of different motifs provided valuable insights into how genetic variation shapes cellular responses and gene expression patterns, underscoring the importance of genetic diversity. Methodological approaches using inducible systems to observe changes in transcription factor binding patterns highlight the critical role of motif variation and redundancy in transcription factor families. These studies provide essential insights into the complex network of transcriptional regulation and chromatin dynamics, revealing the nuanced mechanisms th
