Transfection of the mouse double minute 2 (Mdm2) oncogene has been found to induce immortalization of primary cells and to transform cultured cells. Amplification and/or overexpression of human MDM2 has been documented in a large percentage of human cancers. Mouse and human Mdm2 cDNA have been cloned from transformed cells and the cDNA sequence of both genes have been reported previously. In this report, we present the gene structure of mouse Mdm2. Comparison of the coding sequences of the Mdm2 gene with the previously reported cDNA sequence and with Mdm2 sequences obtained from an Mdm2-bearing cosmid clone capable of inducing transformation revealed that the reported cDNA sequence was in error, and that Mdm2-induced transformation of cells does not require an activating mutation in Mdm2. Ligation-anchor PCR analysis of transcripts produced from the P1 and P2 promoters indicates that transcription initiates at sites upstream of those reported previously for both promoters.
