"Sequence determination of the hemagglutinin-neuraminidase (HN) gene of human parainfluenza type 2 virus and the construction of a phylogenetic tree for HN proteins of all the paramyxoviruses that are infectious to humans.";
Virology 174:308-313(1990).

Comments

FUNCTION: Attaches the virus to sialic acid-containing cell receptors and thereby initiating infection. Binding of HN protein to the receptor induces a conformational change that allows the F protein to trigger virion/cell membranes fusion (By similarity).
FUNCTION: Neuraminidase activity ensures the efficient spread of the virus by dissociating the mature virions from the neuraminic acid containing glycoproteins (By similarity).
CATALYTIC ACTIVITY: Hydrolysis of alpha-(2->3)-, alpha-(2->6)-, alpha-(2->8)- glycosidic linkages of terminal sialic acid residues in oligosaccharides, glycoproteins, glycolipids, colominic acid and synthetic substrates.
SUBCELLULAR LOCATION: Virion membrane; Single-pass type II membrane protein (Potential). Cell membrane; Single-pass type II membrane protein (Potential).
SIMILARITY: Belongs to the paramyxoviruses hemagglutinin-neuraminidase family.
