Gene regulation by cell-type specific TFs controlling neural cell fate specification.

sequence specific TF binding

Description

Transcription factors (TFs) play an important role in regulating transcription and gene expression. Transcriptional regulation is controlled by both general and sequence-specific TFs, as well as their interaction with chromatin factors. In collaboration with Dr. Qi Dai’s lab at Stockholm University, we are investigating transcriptional gene regulation by cell-type specific TFs, BEN-solo family, controlling neural cell fate specification. We are using both genome-wide deep-sequencing approaches (ChIP-seq, ChIP-nexus, ATAC-seq, Pro-seq, RNA-seq, Hi-C), combined with genetics and biochemistry experiments to study their function in the Notch signaling pathway and their interaction with chromatin factors.
