UniProt functional annotation for Q9Q2W5

UniProt code: Q9Q2W5.

Organism: Newcastle disease virus (strain Kansas) (NDV).
Taxonomy: Viruses; ssRNA negative-strand viruses; Mononegavirales; Paramyxoviridae; Paramyxovirinae; Avulavirus.
 
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). Host cell membrane; Single-pass type II membrane protein (Potential).
Similarity: Belongs to the paramyxoviruses hemagglutinin- neuraminidase family.
