The bluetongue virus (BTV) is transmitted by Culicoides biting midges and causes bluetongue (BT), an OIE-notifiable disease of ruminants. At least 29 BTV serotypes are described as determined by the outer shell proteins VP2 and VP5.

Proteolysis of Monomeric Recombinant Rotavirus VP4 Yields an Oligomeric VP5* Core [PDF]
ABSTRACT Rotavirus particles are activated for cell entry by trypsin cleavage of the outer capsid spike protein, VP4, into a hemagglutinin, VP8*, and a membrane penetration protein, VP5*. We have purified rhesus rotavirus VP4, expressed in baculovirus-infected insect cells.

Infectious bursal disease virus VP5 polypeptide: a phosphoinositide-binding protein required for efficient cell-to-cell virus dissemination. [PDF]
Infectious bursal disease virus (IBDV), a member of the Birnaviridae family, is a major avian pathogen responsible for an immunosuppressive disease affecting juvenile chickens. The IBDV genome is formed by two dsRNA segments.

A 3D model of the membrane protein complex formed by the white spot syndrome virus structural proteins. [PDF]
BACKGROUND: Outbreaks of white spot disease have had a large negative economic impact on cultured shrimp worldwide. However, the pathogenesis of the causative virus, WSSV (whit spot syndrome virus), is not yet well understood.

The Kinetics of VP5 mRNA Expression Is Not Critical for Viral Replication in Cultured Cells [PDF]
ABSTRACTWe generated recombinant viruses in which the kinetics of expression of the leaky-late VP5 mRNA was altered. We then analyzed the effect of such alterations on viral replication in cultured cells. The VP5 promoter and leader sequences from positions −36 to +20, containing the TATA box and an initiator element, were deleted and replaced with a ...

The rotavirus VP5*/VP8* conformational transition permeabilizes membranes to Ca 2+
ABSTRACT Rotaviruses infect cells by delivering into the cytosol a transcriptionally active inner capsid particle (a "double-layer particle": DLP). Delivery is the function of a third, outer layer, which drives uptake from the cell surface into small vesicles from which the DLPs escape.

Genetic and phylogenetic analysis of the outer capsid protein genes of Indian isolates of bluetongue virus serotype-16 [PDF]
Aim: The aim of the study was to characterize bluetongue virus serotype 16 (BTV-16), recently isolated from different states of India. The evolutionary relationship of newly isolated BTV-16 and previously reported Indian and global BTV-16 isolates were ...

Alternative intermolecular contacts underlie the rotavirus VP5* two‐ to three‐fold rearrangement [PDF]
The spike protein VP4 is a key component of the membrane penetration apparatus of rotavirus, a nonenveloped virus that causes childhood gastroenteritis. Trypsin cleavage of VP4 produces a fragment, VP5*, with a potential membrane interaction region, and primes rotavirus for cell entry.
