HPK1 (human)

Overview
HPK1 a protein kinase of the STE20 family. Expressed primarily in hematopoietic organs, including bone marrow, spleen and thymus. Also expressed at very low levels in lung, kidney, mammary glands and small intestine. May play a role in hematopoietic lineage decisions and growth regulation. Positively regulated by PGE2 and a negative regulator of PGE2-induced FOS gene transcription. Note: This description may include information from UniProtKB.
Protein type: EC 2.7.11.1; Kinase, protein; Protein kinase, Ser/Thr (non-receptor); Protein kinase, STE; STE group; STE20 family; KHS subfamily
Cellular Component: cytoplasm
Molecular Function: protein serine/threonine kinase activity; protein binding; MAP kinase kinase kinase kinase activity; ATP binding; small GTPase regulator activity; protein kinase activity
