Protein attributes
| Sequence length | 568 AA. |
| Sequence status | Complete. |
| Protein existence | Inferred from homology |
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. |
