Target-based drug development depends heavily on characterizing druggable pockets, which are protein areas with the capacity to bind organic small molecules. Nevertheless, the process of obtaining pocket descriptors is complex, and the effectiveness of current approaches is frequently restricted. Researchers present PocketVec, a method for creating pocket descriptors by virtually screening lead-like compounds inversely. PocketVec addresses significant issues and performs similarly to leading techniques. Furthermore, researchers employ experimentally established structures and AlphaFold2<\/a> models to extensively search the human proteome for druggable pockets, finding over 32,000 binding sites across 20,000 protein domains. Next, researchers create PocketVec descriptors for every site and carry out a comprehensive search for similarities, examining more than 1.2 billion pairwise comparisons. The findings show clusters of similar pockets in proteins lacking crystallized inhibitors and open the door to ways to prioritize chemical probe development to investigate the druggable space. These findings indicate commonalities in druggable pockets not detected by structure- or sequence-based methods.<\/em><\/p>\n\n\n\n

Introduction<\/h2>\n\n\n\n

Protein segments known as ligand binding sites engage in biochemical interactions with peptides and other organic small molecules. Eventually, the process of binding causes the protein’s function to be selectively modulated. In fact, one of the most effective methods in traditional drug development is to find tiny compounds that either activate or inhibit a protein linked to a disease based on the high-resolution three-dimensional structure of binding sites.<\/p>\n\n\n\n

With the increasing availability of protein structures, the Protein Data Bank (PDB) is a useful tool for the early phases of drug development. Protein-small molecule docking is one example of a structure-based technique that is essential for improving drug design and reducing the risk of clinical trial failure. However, direct comparisons between other proteins and protein families are not possible due to the target-dependent nature of scoring functions<\/a>. Proteome-wide analyses frequently employ alternative techniques such as interaction fingerprint comparison, binding site similarity assessment, and reverse pharmacophore screening.<\/p>\n\n\n\n
