CC -!- CATALYTIC ACTIVITY: Hydrolysis of alpha-(2->3)-, alpha-(2->6)-, CC alpha-(2->8)- glycosidic linkages of terminal sialic acid residues CC in oligosaccharides, glycoproteins, glycolipids, colominic acid CC and synthetic substrates. {ECO:0000256|HAMAP-Rule:MF_04071, CC ECO:0000256|RuleBase:RU361252, ECO:0000256|SAAS:SAAS00114528}. CC -!- COFACTOR: CC Name=Ca(2+); Xref=ChEBI:CHEBI:29108; Evidence={ECO:0000256|HAMAP- CC Rule:MF_04071, ECO:0000256|RuleBase:RU361252, CC ECO:0000256|SAAS:SAAS00612833}; CC -!- ACTIVITY REGULATION: Inhibited by the neuraminidase inhibitors CC zanamivir (Relenza) and oseltamivir (Tamiflu). These drugs CC interfere with the release of progeny virus from infected cells CC and are effective against all influenza strains. Resistance to CC neuraminidase inhibitors is quite rare. {ECO:0000256|HAMAP- CC Rule:MF_04071, ECO:0000256|SAAS:SAAS01070481}. CC -!- SUBUNIT: Homotetramer. {ECO:0000256|HAMAP-Rule:MF_04071, CC ECO:0000256|RuleBase:RU361252, ECO:0000256|SAAS:SAAS00114476}. CC -!- SUBCELLULAR LOCATION: Host apical cell membrane CC {ECO:0000256|SAAS:SAAS00582107}; Single-pass type II membrane CC protein {ECO:0000256|SAAS:SAAS00582107}. CC -!- DOMAIN: Intact N-terminus is essential for virion morphogenesis. CC Possess two apical sorting signals, one in the ectodomain, which CC is likely to be a glycan, and the other in the transmembrane CC domain. The transmembrane domain also plays a role in lipid raft CC association. {ECO:0000256|HAMAP-Rule:MF_04071}. CC -!- PTM: N-glycosylated. {ECO:0000256|HAMAP-Rule:MF_04071, CC ECO:0000256|RuleBase:RU361252}. CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 34 family.
