Protein
Hemagglutinin-neuraminidase
Gene
HN
Organism
Newcastle disease virus (strain Chicken/United States/B1/48) (NDV)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

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.
Neuraminidase activity ensures the efficient spread of the virus by dissociating the mature virions from the neuraminic acid containing glycoproteins By similarity.

Catalytic activityi

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.
