Immunopharmacology Comments
HPK1 inhibits T-cell receptor (TCR) signaling via a mechanism that induces phosphorylation and ubiquitination of SLP-76, it inhibits B-cell receptor signaling by inducing phosphorylation and ubiquitination of BLNK [9].

Physiological Consequences of Altering Gene Expression
Mice with hpk1 knock-out show enhanced T cell activation, increased cytokine production, and increased antibody production after KLH immunization. These findings confirm that hpk1 is a negative regulator of T cell receptor signalling and T cell-mediated immune responses.

General Comments
Hematopoietic progenitor kinase 1 (HPK1) regulates stress responses, proliferation, and apoptosis in hematopoietic cells. HPK1 has been identified as a novel target for cancer immunotherapy, whose inhibition may activate anti-tumour activity of both dendritic cells and T cells [6]. In contrast, a specific role of HPK1 as a novel tumor suppressor has been suggested by studies in pancreatic cancer [8].
