Uncovering Bifunctional Molecules that Induce Post-translational Modifications

9:00 am Bifunctional Modalities for Repurposing Protein Function

  • Amit Choudhary Assistant Professor of Medicine, Harvard Medical School

9:30 am Expanding the Scope of Induced Proximity

Synopsis

  • Induced Proximity has a multitude of potential applications for drug discovery
  • Post-translational modifications dominate cell signalling and are often misregulated in disease
  • Chemical biology technologies enable us to control PTMs for therapeutic benefit

10:00 am Writing & Erasing O-GlcNAc from Target Proteins in the Cell

Synopsis

  • Over 15% of the cellular proteome is modified by O-linked N-acetyl glucosamine (O-GlcNAc), a post-translational modification (PTM) that consists of a single sugar attached to serine or threonine residues of nuclear, cytosolic and mitochondrial proteins
  • Due to the ubiquitous nature of the modification, O-GlcNAc has been implicated in numerous biological processes, including immune response, cancer progression, neurodegenerative disease, and diabetes
  • We have now developed a cellular approach for writing and erasing O-GlcNAc from target proteins in the cell. The method uses a nanobody fused to an O-GlcNAc writer or eraser to control O-GlcNAc levels on the desired target protein
