The Sfpi-1 proviral integration site of Friend erythroleukemia encodes the ets-related transcription factor Pu.1

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 laborato…
