    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
    6. We found levels of CHKA to be increased in human HCCs compared to nontumor tissues, and increased expression to be associated with tumor aggressiveness. Overexpression of CHKA in HCC cell lines increased their invasiveness, resistance to EGFR inhibitors, and ability to form metastatic tumors in mice by promoting interaction of EGFR with mechanistic target of rapamycin complex 2. 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. PMID: 27489281
