Crystal engineering of the hepatoma-derived growth factor-related protein 2 PWWP domain towards crystallographic fragment screening.

ABSTRACT: Hepatoma-derived growth factor-related protein 2 (HRP-2) is a member of the HDGF-related protein family, which has been linked to multiple malignancies. A defining feature of this protein family is the presence of an N-terminal PWWP domain, which enables binding to nucleosomes carrying a dimethylation or trimethylation marker on residue Lys36 of histone H3. To support the rational design of small-molecule drugs that bind to the PWWP domain, crystallographic fragment screening was chosen. A critical requirement for such screening is the ability to reliably produce large batches of high-quality crystals, ideally grown under low-salt conditions to prevent the precipitation of drug-like fragments during crystal soaking. Initial crystallization of the wild-type (WT) HRP-2 PWWP domain only produ
