靶点详情

  • 功能：
    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. Together with CLNK, it enhances CD3-triggered activation of T-cells and subsequent IL2 production.

    2. HPK1 protein expression, which is expressed at significantly higher levels in NATs compared with paired IDC-NOS tissues, is significantly negatively associated with ER positivity and is positively associated with OS duration, suggesting that HPK1 may exhibit anticancer activities. PMID: 28765906
    3. CUL7/Fbxw8 ubiquitin ligase-mediated HPK1 degradation revealed a direct link and novel role of CUL7/Fbxw8 ubiquitin ligase in the MAPK pathway, which plays a critical role in cell proliferation and differentiation. PMID: 24362026

    7. QVD and 1,25D-induced differentiation was accompanied by increased signaling by Hematopoietic Progenitor Kinase 1(HPK1), and the expression of transcription factors known to be involved in monocytic differentiation was increased. PMID: 22541691
    8. HPK1 negatively regulates T cell activation by reducing the persistence of signaling microclusters. PMID: 22105350

    10. The catalytic activity of a hematopoietic cell-restricted, Ste20-related S/TPK, HPK1, is positively regulated by exposure to physiological concentrations of PGE2. HPK1 is a negative regulator of PGE2-induced FOS gene transcription. PMID: 12522005
    11. PP4 is a positive regulator for HPK1 and the HPK1-JNK signaling pathway PMID: 15364934
