Introduction to Probe My Pathway (PMP)

Introduction to Probe my pathway (PMP): accessible at apps.thesgc.org/pmp/   Despite the sequence of the whole human genome 20 years ago, our knowledge of the human proteome remains fragmented. While ~65% of the human proteome has been investigated in varying degrees, about 35% of the human proteome remains uncharacterized (the ‘dark proteome’). A key obstacle Read More …

Distinguishing between catalytic and non-catalytic pockets in the ligandable human genome: InterPro analysis

As describe in my previous post, my goal is to discover non-catalytic druggable pockets in human enzymes. These pockets could potentially be exploited for the design of ProxPharm compounds (chimeric compounds that bring two proteins in close proximity to elicit an effect of one protein on the other1). An essential aspect for the design of Read More …

Distinguishing between catalytic and non-catalytic pockets in the ligandable human genome

My goal is to find druggable pockets in human enzymes that are non-catalytic. These non-catalytic druggable pockets may then be exploited for proximity pharmacology (ProxPharm), a novel paradigm in drug discovery where chimeric compounds bring two proteins in close proximity to elicit an effect of one protein on the other1. For example, PROTACs simultaneously bind Read More …

Druggability and Genetic Variability of the ADP-bound Pocket of SARS-CoV-2 RNA-dependent RNA polymerase NiRAN domain Across Coronaviruses and SARS-CoV-2 Samples – Post 22

The RNA-dependent RNA-polymerase (RdRp) also known as non-structural protein 12 (nsp12) is the target of antiviral agent remdesivir. Nsp12 has an important role in viral genome replication and transcription. (Chen et al., 2020)  Chen et al. identified a new pocket on the N-terminal extension of nsp12 occupied by ADP-Mg2+ after solving the structure of the helicase-polymerase complex. This ADP-bound pocket is on the N-terminal nidovirus RdRp-associated nucleotidyltransferase (NiRAN) domain which Read More …

A Gentle Introduction to The Ligandable Genome Project

Previously in our lab, Jiayan Wang et al. worked on a project related to the druggable genome. In her project, she evaluated the druggability of protein domains found in the human genome using protein structures bound to druglike ligands. The left panel in Figure 1 demonstrates her workflow to define ligand binding pockets. To build Read More …
