Hemagglutinin-esterase
From Proteopedia
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.
