    Hello PDPD Community!

    An interesting article recently published by Wozniak et al in Nature: Enhanced mapping of small-molecule binding sites in cells - Nature Chemical Biology.

    Incredibly powerful new tool to help identify binding sites on target proteins for small molecules - potentially a technique to identify binding sites for novel therapeutics across the proteome. As a small molecule medicinal chemist myself, this is rather exciting and intriguing - imagine the potential for novel small molecule modalities that could be identified and designed!

    Enhanced mapping of small-molecule binding sites in cells - Nature Chemical Biology
    Photoaffinity probes are routinely utilized to identify proteins that interact with small molecules. However, despite this common usage, resolving the specific sites of these interactions remains a challenge. Here we developed a chemoproteomic workflow to determine precise protein binding sites of photoaffinity probes in cells.

    Can you share a pdf file for the paper?

    Thanks,

    Hey Kilyoung! Thanks for your reply. Unfortunately it is against publication policy to share the pdf publicly, as subscription access is needed for Nature. Apologies for this.

    A nice article. I am curious to know if the enhanced mapping is peculiar to either covalent or  noncovalent interactions or both.

    Hi Bo,

    Thank you for sharing this article. Very interesting article that provides a robust method for high-resolution mapping of reversible small-molecule interactions with proteins.
