Function

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^[1]. The HE is a trimer and each monomer contains 3 domains: the membrane fusion domain, the esterase domain and the receptor-binding domain.
