摘要

It is important for Influenza virus infection that the viral surface glycoprotein, hemagglutinin (HA) be cleaved by host cell derived protease. The HA molecule is activated by the host cell-derived protease at a specific cleavage site of non-activatedHA (HAO) having a molecular weight of 75 kDa, and is divided into parts to the HA1 molecule of 55 kDa and the HA2 molecule of 25 kDa. If the conformational change of the HA molecule under acidic pH occurs, the hydrophobic region in the HA2 molecule at the N terminal end is exposed, and the membrane fusion between the cell and the virus is promoted.
