Protein Domain : Viral late protein H2 IPR005023

Type	Family
Description	This entry represents the late protein H2 found in Vaccinia and other poxviruses. This protein is a highly conserved viral membrane protein found in all sequenced poxviruses, containing an N-terminal transmembrane domain and four conserved cysteines thought to be involved in the formation of intramolecular disulphide bonds [ ]. H2 has been shown to be necessary for entry into the host cell and virus-induced cell-cell fusion, but is not required for virus morphogenesis or the attachment of virus particles to cells. It is part of an entry-fusion complex composed of eight viral membrane proteins [].
