| abstractText | Previous studies identified a common site (Sfpi-1) for proviral integration in immortalized Friend erythroleukemias. cDNAs corresponding to a 1.5-kb Sfpi-1 mRNA were isolated and sequenced. These were larger than an independently isolated Sfpi-1 cDNA described by researchers from another laboratory, and they contained common differences from that sequence, including in the coding region four extra nucleotides that altered the reading frame. The properly translated protein is identical to Pu.1, a transcription activation factor that is related to the ets oncogene family. Genetic methods were used to map Sfpi-1 with respect to other loci on mouse chromosome 2. Our results suggest that Pu.1 blocks erythroblast differentiation and thereby causes immortalization. |
