RT   "Nucleotide and deduced amino acid sequence of hemagglutinin-neuraminidase
RT   genes of human type 3 parainfluenza viruses isolated from 1957 to 1983.";
RL   Virology 162:137-143(1988).
CC   -!- FUNCTION: Attaches the virus to sialic acid-containing cell receptors
CC       and thereby initiating infection. Binding of HN protein to the receptor
CC       induces a conformational change that allows the F protein to trigger
CC       virion/cell membranes fusion (By similarity). {ECO:0000250}.
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}.
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   -!- SUBCELLULAR LOCATION: Virion membrane {ECO:0000305}; Single-pass type
CC       II membrane protein {ECO:0000305}. Host cell membrane {ECO:0000305};
CC       Single-pass type II membrane protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the paramyxoviruses hemagglutinin-neuraminidase
CC       family. {ECO:0000305}.
