ID: 0gkonrzw_9
Snippet: IAV can perturb the trans-Golgi network (TGN) using its M2 viroporin to affect the secretory pathway in the host. In addition to its role in virus uncoating, the ion channel activity of M2 is required for the trafficking and processing of viral proteins, such as the HA glycoprotein [11] as well as M2 itself. Expression of M2 delayed its presentation at the cell surface, which could be prevented using a viroporin inhibitor, amantadine. Using its p.....
Document: IAV can perturb the trans-Golgi network (TGN) using its M2 viroporin to affect the secretory pathway in the host. In addition to its role in virus uncoating, the ion channel activity of M2 is required for the trafficking and processing of viral proteins, such as the HA glycoprotein [11] as well as M2 itself. Expression of M2 delayed its presentation at the cell surface, which could be prevented using a viroporin inhibitor, amantadine. Using its proton channel activity, M2 prevents the acidification of the trans-Golgi, resulting in delay of protein trafficking through the TGN [12] . By doing so, M2 helps to coordinate the presentation and maturation of the viral glycoprotein on the membrane with viral assembly [12] [13] [14] .
