- Rous sarcoma virus
Taxobox Color parameter is not needed automatically assigned name Rous sarcoma virus virus group vi familia Retroviridae subfamilia Orthoretrovirinae genus Alpharetrovirus species Rous sarcoma virus Rous sarcoma virus RSV is a retrovirus and is the first oncovirus to have been described it causes sarcoma in chickens. As with all retroviruses, it reverse transcribes its RNA genome into cDNA before integration into the host DNA. History RSV was discovered in 1911 by Peyton Rous , working at Rockefeller University in New York City, by injecting cell free extract of chicken tumour into healthy Plymouth Rock chickens. The extract was found to induce oncogenesis . The tumour was found to be composed of connective tissue a sarcoma . Rous was awarded the Nobel Prize for the significance of his discovery in 1966 .

RSV has three genes gag gene gag encodes capsid proteins pol gene pol encodes reverse transcriptase It lost the env gene normally seen in avian retroviruses during the recombination events that allowed it to acquire src src gene src encodes a tyrosine kinase that attaches phosphate groups to the amino acid tyrosine in host cell proteins. The RSV genome has terminal repeat s enabling its integration into the host genome and also overexpression of RSV genes. src gene The Src gene src gene is oncogene oncogenic as it triggers uncontrolled growth in abnormal host cells. It is an acquired gene, found to be present throughout the animal animal kingdom with high levels of conservation between species. The src gene w ... more details
