In molecular biology haemagglutinin-esterase fusion glycoprotein (HEF) is a multi-functional protein embedded in the viral envelope of several viruses including influenza C virus coronaviruses and toroviruses. HEF is required for infectivity and functions to recognise the host cell surface receptor to fuse the viral and host cell membranes and to destroy the receptor upon host cell infection.
