Research Abstract

Polymorphisms at the mouse APOBEC3(mA3) gene locus have been associated with different susceptibilities to infection with mouse leukemia viruses. In virus-resistant C57BL/6(B6) mice, mA3 transcripts and protein are more abundant than those in susceptible BALB/c mice, and these strains of mice also express mA3 transcripts with different splicing patterns. B6 mice express predominantly the exon 5-deficient transcript, which confer more efficient translation than the full-length transcript. By employing in vitro splicing assays using genomic DNA clones, we identified two critical determinants that regulate exon 5 inclusion into mA3 transcripts : the number of TCCT repeats upstream of exon 5 and the newly identified single nucleotide polymorphism within exon 5 located 12 bases upstream of the exon 5/intron 5 boundary.
