General annotation (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.

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.

Sequence similarities

Belongs to the paramyxoviruses hemagglutinin-neuraminidase family.
