Beyond the chromosome: unravelling the interplay between inter-chromosomal genome architecture and mRNA biogenesis
TRANS-3 aims to uncover the mechanisms and functions of inter-chromosomal genome structure through studying mRNA factories and their regulatory roles in gene expression and disease.
Projectdetails
Introduction
In TRANS-3 we will develop the theoretical and experimental framework to understand inter-chromosomal genome structure and activity. Despite advances in sequencing chromosomes and mapping their three-dimensional (3D) organization, a full picture of 3D genome structure that details how the borders of various chromosome territories functionally interface with one another is still missing.
Analogy
As an analogy, our world map does not indicate most natural corridors or manmade infrastructure that connect countries to one another. Worse, we barely understand how such connections function.
Recent Findings
My recent work has identified one of the few functional inter-chromosomal (trans) DNA interactions known to date: a splicing factory involving over ten chromosomes and orchestrated by the muscle-specific protein RBM20 around its key target, the TTN pre-mRNA.
Hypothesis
I hypothesize that this exemplifies how mRNA biogenesis instructs the formation of trans-interacting chromatin domains (TIDs) around mRNA factories, nuclear compartments that facilitate gene regulation.
Research Objectives
We will test this general hypothesis by dissecting the mechanisms and function of a specific, disease-relevant model: the RBM20 mRNA splicing factory. We will then explore the global impact of these regulations.
Work Packages
-
WP1: We will mechanistically assess how mRNA factories form and act through live imaging of the nuclear positioning and alternative splicing dynamics of an RBM20-regulated locus.
-
WP2: We will examine the physiological role of mRNA factories by studying the effects of disease-associated mutations in RBM20 and the TTN regulator GATA4, and of genetic variability in TTN regulatory regions.
-
WP3: We will develop and deploy a novel pipeline to identify, validate, and study new TIDs and mRNA factories through the combination of molecular biology, bioinformatics, biochemistry, and single-cell biology.
Conclusion
In all, TRANS-3 will venture beyond the chromosome frontier towards a deeper understanding of nuclear structure-function.
