Target
Hck
Molecular classification
Enzyme, Protein Kinase, Tyrosine Kinase, Non-receptor tyrosine kinase, Src family kinase (SFK)
01

Overview

Hck (hematopoietic cell kinase) is a non-receptor tyrosine-protein kinase belonging to the Src family of kinases (SFKs). It is primarily expressed in myeloid and B-lymphocyte lineage cells, where it plays a crucial role in immune cell signaling, inflammation, and cellular processes like phagocytosis and migration. Hck regulates actin-dependent processes, participates in NLRP3 inflammasome formation, and modulates LPS-induced inflammatory responses. Dysregulation of Hck is implicated in various inflammatory diseases, making it a potential therapeutic target.
