Background Hematopoietic progenitor kinase 1 (HPK1) is a member of the germinal center kinases that is predominantly expressed in hematopoietic cells. HPK1 is a key component linking T or B cell receptors to SAPK/JNK and IkappaB kinase pathways in lymphocytes (1-3). Through its proline-rich motif, HPK1 associates with multiple SH3 domain-containing adaptor proteins, including GRB2, Nck, Crk, SLP-76, and BLNK. Phosphorylation of Tyr379 by Syk is necessary for HPK1 association with BLNK and SLP-76, as well as for HPK1 activity (4,5). Caspase cleavage of HPK1 also modulates the biological function of HPK1 (3,6,7).
