CC -!- FUNCTION: Mediates the viral entry into the host cell together with
CC fusion/F protein. Attaches the virus to sialic acid-containing cell
CC receptors and thereby initiates infection. Binding of HN protein to the
CC receptor induces a conformational change that allows the F protein to
CC trigger virion/cell membranes fusion. {ECO:0000250|UniProtKB:Q91UL0}.
CC -!- FUNCTION: Neuraminidase activity ensures the efficient spread of the
CC virus by dissociating the mature virions from the neuraminic acid
CC containing glycoproteins. {ECO:0000250|UniProtKB:Q91UL0}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Hydrolysis of alpha-(2->3)-, alpha-(2->6)-, alpha-
CC (2->8)- glycosidic linkages of terminal sialic acid residues in
CC oligosaccharides, glycoproteins, glycolipids, colominic acid and
CC synthetic substrates.; EC=3.2.1.18;
CC Evidence={ECO:0000250|UniProtKB:Q91UL0};
CC -!- SUBUNIT: Homodimer. Forms homotetramers. Interacts with fusion/F
CC protein. Interacts with host CG-1B; this interaction inhibits viral
CC adsorption and replication rather than internalization.
CC {ECO:0000250|UniProtKB:Q91UL0}.
CC -!- SUBCELLULAR LOCATION: Virion membrane {ECO:0000250|UniProtKB:Q91UL0};
CC Single-pass type II membrane protein {ECO:0000250|UniProtKB:Q91UL0}.
CC Host cell membrane {ECO:0000250|UniProtKB:Q91UL0}; Single-pass type II
CC membrane protein {ECO:0000250|UniProtKB:Q91UL0}.
CC -!- SIMILARITY: Belongs to the paramyxoviruses hemagglutinin-neuraminidase
CC family. {ECO:0000305}.
