Title: Sequence basis of transcription Initiation in human genome
3 April 2024 5:30 p.m. - 6:30 p.m. Central European Time

Speaker: Kseniia Dudnyk, Jian Zhou lab, UT Southwestern Medical Center

Abstract:

Transcription initiation is an essential process for ensuring proper function of any gene, however, we still lack a unified understanding of sequence patterns and rules that explains most transcription initiation sites in human genome. By explaining transcription initiation at basepair resolution from sequence with a deep learning-inspired explainable modeling approach, we show that simple rules can explain the vast majority of human promoters. We identified key sequence patterns that contribute to human promoter function, each activating transcription with a distinct position-specific effect curve that likely reflects its mechanism of promoting transcription initiation. Most of these position-specific effects have not been previously characterized, and we verified them using experimental perturbations of transcription factors and sequences. We revealed the sequence basis of bidirectional transcription at promoters and links between promoter selectivity and gene expression variation across cell types. Additionally, by analyzing 241 mammalian genomes and mouse transcription initiation site data, we showed that the sequence determinants are conserved across mammalian species. Taken together, we provide a unified model of the sequence basis of transcription initiation at the basepair level that is broadly applicable across mammalian species, and shed new light on basic questions related to promoter sequence and function.
