Crystal structure of HPK1 (MAP4K1) kinase in complex with 5-{[4-{[(1S)-2-HYDROXY-1-PHENYLETHYL]AMINO}-5-(1,3,4-OXADIAZOL-2-YL)PYRIMIDIN-2-YL]AMINO}-3,3-DIMETHYL-2-BENZOFURAN-1(3H)-ONE
Structural highlights
FunctionM4K1_HUMAN Serine/threonine-protein kinase, which may play a role in the response to environmental stress. Appears to act upstream of the JUN N-terminal pathway. May play a role in hematopoietic lineage decisions and growth regulation. Able to autophosphorylate.[1] [2] Publication Abstract from PubMedHematopoietic progenitor kinase 1 (HPK1) is an intracellular kinase that plays an important role in modulating tumor immune response and thus is an attractive target for drug discovery. Crystallization of the wild-type HPK1 kinase domain has been hampered by poor expression in recombinant systems and poor solubility. In this study, yeast surface display was applied to a library of HPK1 kinase-domain variants in order to select variants with an improved expression level and solubility. The HPK1 variant with the most improved properties contained two mutations, crystallized readily in complex with several small-molecule inhibitors and provided valuable insight to guide structure-based drug design. This work exemplifies the benefit of yeast surface display towards engineering crystallizable proteins and thus enabling structure-based drug discovery. Using yeast surface display to engineer a soluble and crystallizable construct of hematopoietic progenitor kinase 1 (HPK1).,Lau WL, Pearce B, Malakian H, Rodrigo I, Xie D, Gao M, Marsilio F, Chang C, Ruzanov M, Muckelbauer JK, Newitt JA, Lipovsek D, Sheriff S Acta Crystallogr F Struct Biol Commun. 2021 Jan 1;77(Pt 1):22-28. doi:, 10.1107/S2053230X20016015.
