Publication number: 20120322156Abstract: In accordance with the present invention, a family of membrane fusion protein and polynucleotides encoding the proteins have been identified. The proteins and nucleotides are derived from the family Reoviridae. Two membrane fusion proteins have been isolated from reoviruses isolated from poikilothermic hosts: the p14 protein from reptilian reovirus (RRV) isolated from python, and the p16 protein from aquareovirus (AQV) isolated from salmon. The genes encoding these proteins have been cloned and sequenced. Analysis of the amino acid sequences of these proteins show that both lack the typical fusion peptide motif found in other membrane fusion proteins. Expression of these proteins in cells results in cell-cell fusion.Type: ApplicationFiled: August 24, 2012Publication date: December 20, 2012Applicant: INNOVASCREEN, INC.Inventor: Roy Duncan
