Orbivirus VP3 (T2) protein
The orbivirus VP3 protein is part of the virus core and makes a 'subcore' shell made up of 120 copies of the 100K protein. VP3 particles can also bind RNA and are fundamental in the early stages of viral core formation. Also found in the family is structural core protein VP2 from broadhaven virus which is similar to VP3 in bluetongue virus. Orbivirus are part of the larger reoviridae which have a dsRNA genome of 10-12 linear segments; orbivirus found in this family include bluetongue virus and epizootic hemorrhagic disease virus.
