  • Relevance
    Middle T antigen (MT) is a 421-amino-acid protein associated with membranes and underlying cytoskeletal elements, and is associated with a tyrosine-specific protein kinase activity. It is the principal oncoprotein of polyomavirus that is necessary and often sufficient for transformation in vitro. MT delivered as a transgene or a retrovirus can induce tumors in a wide variety of tissues. Polyomavirus (PyV) is a small, double-stranded, closed-circular-DNA virus with an approximately 5-kb genome divided into two roughly equal regions. The late transcripts produce the viral capsid proteins, whereas the early region encodes three so-called tumor (T) antigens that are important for both productive infection and transformation.
