physiological function | acylglycerol kinase (AGK) is a multisubstrate lipid kinase, that catalyzes the production of lysophosphatidic acid and phosphatidic acid from monoacylglycerol and diacylglycerol. Acylglycerol kinase augments JAK2/STAT3 signaling in esophageal squamous cells, the enzyme AGK directly interacts with the JH2 domain to relieve inhibition of JAK2 and activate JAK2/STAT3 signaling. AGK levels significantly correlate with increased STAT3 phosphorylation, poorer disease-free survival, and shorter overall survival in primary esophageal squamous cell cancer cell, and AGK expression is significantly correlated with JAK2/STAT3 hyperactivation in esophageal squamous cell cancer cell, as well as in lung and breast cancer. Overexpression of AGK leads to activation of EGF receptor and promotes the proliferation and migration of prostate cancer cells, suggesting that AGK might act as a potent oncogene. AGK enhances JAK2 activity by blocking JH2-mediated autoinhibition of JAK2. Solid tumor cells override the autoinhibitory effect of JH2 to maintain activation of JAK2/STAT3 signaling, mechanism, overview. Enzyme AGK is a JH2 domain-interacting protein that activates the JAK2/STAT3 pathway | Homo sapiens |
