'''Hemagglutinin-esterase''' (HE) is a glycoprotein of the envelopes of some viruses. HE recognizes the host cell surface receptor - a sialic acid derivative. The esterase region of the HE is responsible for the destruction of the receptor<ref>PMID:16575523</ref>.

'''Hemagglutinin-esterase''' (HE) is a glycoprotein of the envelopes of some viruses. HE recognizes the host cell surface receptor. The esterase region of the HE is responsible for the destruction of the receptor. The HE is a trimer and each monomer contains 3 domains: the membrane fusion domain, the esterase domain and the receptor-binding domain.
