title: Enhanced levels of multicatalytic proteinase mRNAs in Rous sarcoma virus transformed cells.
abstract: The multicatalytic proteinase (proteasome; MCP) is a high molecular mass proteinase which is found in all eukaryotic cells. Northern blot analysis of the levels of MCP mRNAs in a Rat-1 fibroblast cell line and in cells transformed with Rous sarcoma virus showed marked increases in the transformed cells. However, the results of immunoblot analysis with anti-MCP antibodies suggested that the MCP protein content of the two cell lines was similar.
