Function

Designed to protect mice from H1N1 by masking the cell surface receptors recognized by influenza virion preventing viral binding and entry into the host cells.

Relevance

Influenza binds to sialic acid receptors present on the respiratory epithelium, eventually gaining access through endocytosis.[3] By potentially concealing sialic acid receptors, it has been proposed that a sialic acid binding protein would aid in prevention of influenza infection.
