Structure. 2018; 27 ( this issue) : 125-133 Google Scholar report several apo and small-molecule inhibitor-bound structures of the kinase domain of hematopoietic progenitor kinase 1, a ser/thr kinase that functions as an inhibitor of T cell activation. The studies reveal that the HPK1 kinase domain exists as a domain-swapped dimer %U https://www.cell.com/structure/fulltext/S0969-2126(18)30465-9
