Gene Ontology (GO) annotations related to this gene include transferase activity, transferring phosphorus-containing groups and protein tyrosine kinase. Cancer Cell, 2020 Oct 12. Tarus Therapeutics Seeks to Initiate Clinical Trial of TT-10 (A2AR antagonist) in Cancer Patients Adicet Bio Announces Initiation of its First-in-Human Phase 1 Trial of ADI-001 for the Treatment. Sunitinib, a multi-receptor tyrosine kinase (RTK) inhibitor approved for the management of gastrointestinal stromal tumors (GISTs), renal cell carcinoma (RCC), and pancreatic cancer, has been reported to inhibit HPK1 in vitro In this report, we describe the crystal structures of the native HPK1 kinase domain in both nonphosphorylated and doubly. HPK1 structures also revealed the existing relationship between the AS and the domain-swapped dimers. Recently, the first HPK1-targeting PROTAC, SS47 (Fig. Cancer Discov; 8(10); 1210-2.
