5. hCKalpha functions as an indispensable regulator that bridges PI4KIIIalpha and hepatitis C virus NS5A and potentiates NS5A-stimulated PI4KIIIalpha activity, which then facilitates the targeting of the ternary complex to the endoplasmic reticulum for viral replication. PMID: 28566381

PMID: 28065789
7. These findings demonstrate that hCKalpha forms a complex with hepatitis C virus NS5A and that hCKalpha activity enhances the targeting of the complex to the endoplasmic reticulum, where hCKalpha protein, not activity, mediates NS5A binding to NS5B, thereby promoting functional membranous viral replication complex assembly and viral RNA replication.

20. pharmacological inhibition of ChoKalpha induces cancer cell death through a mechanism that involves the activation of exaggerated and persistent ER stress supported by CHOP overproduction. PMID: 24287694

25. A combination of initial velocity and product inhibition studies, together with the kinetic and structural characterisation of a novel ChoKalpha inhibitor is used to support a mechanism of action for human ChoKalpha. PMID: 23416529
26. HK2 and CKA expression may have biologic and prognostic significance in hepatocellular carcinoma, with tumor HK2 expression being a potential independent predictor of survival. PMID: 23071593
27. ASAH1 inhibition synergistically sensitizes lung cancer cells resistant to the antiproliferative effect of choline kinase alpha inhibitors. PMID: 22515519
28. Data show choline kinase alpha (CHKalpha) expressed in both cytoplasm and nucleus in malignant lesions. PMID: 22038995
29. these results strongly implicate a new c-Src-dependent link between CHKA and EGFR, which contributes to the regulation of cell proliferation and tumorigenesis. PMID: 21822308
