H3N2 NA ( H274Y )蛋白背景综述
Neuraminidase ( NA ) is a major membrane glycoproteins found on the surface of influenza virus. NA specifically catalyzes the hydrolysis removal of terminal sialic acid residues from viral and cellular glycoconjugates. It is known that HA binds to the sialic acid-containing receptors on the surface of host cells during initial infection, and at the end of an infectious cycle, NA cleaves the HA-sialic acid bondage from the newly formed virions and the host cell receptors during budding. NA thus is described as a receptor-destroying enzyme which facilitates virus release and efficient spread of the progeny virus from cell to cell. NA is a single-pass type I I membrane protein which exists as a homotetramer, and the transmembrane domain is involved in lipid raft association during intracellular transport. NA is suggested to play a role in the determination of host range restriction on replication and virulence. Nine subtypes of NA have been identified, and subtypes N1 and N2 have been positively linked to epidemics in man.
