Alternative polyadenylation of the mouse <b><i>Dazap1</i></b><b> transcripts.</b>

<p>(<b><i>A</i></b>) Sequence of the <i>Dazap1</i> 3′ UTR (NM_133188, nt1378–2093). The polyadenylation signals (PASs) are in bold capital letters, and the polyadenylation sites determined by 3′RACE are marked with arrows. The CU-rich region is indicated with heavy underline, and the AU-rich region with two AUUUA motifs (in bold italic) is indicated with light underline. (<b><i>B</i></b>) 3′RACE products of <i>Dazap1</i> transcripts in adult mouse testes. (<b><i>C</i></b>) Diagram of the <i>Dazap1</i> cDNA. The locations of Northern hybridization probes are indicated. The arrows point to the three PASs. (<b><i>D</i></b>) Northern analyses of <i>Dazap1</i> transcripts in adult mouse testes. Ethidium bromide (EtBr) staining of the 18 S rRNA is shown at bottom as a loading control.
