Viral attachment sigma 1, reoviral (IPR002592)

Short name: Vir_attach_sigma1_reovir

Overlapping homologous superfamilies

Family relationships



This family consists of the Reovirus sp. sigma 1 haemagglutinin, cell attachment protein. This glycoprotein is a minor capsid protein and also determines the serotype-specific humoral immune response. Sigma 1 consist of a fibrous tail and a globular head. The head has important roles in the cell attachment function of sigma 1 and determinant of the type-specific humoral immune response [PMID: 2398530]. Reovirus sp. are part of the Orthoreovirus group of Reoviridae with a dsRNA genome. Also present in this family is Bacteriophage SF6 lysozyme P21270.
