The nuclei of mammalian cells contain domains, termed nuclear speckles, which are enriched in splicing factors and poly(A) RNA. Although nuclear speckles are thought to represent reservoirs from which splicing factors are recruited to sites of transcription and splicing, the presence of poly(A) RNA in these structures remains enigmatic. An additional component of the speckles is poly(A) binding protein 2 (PABP2), a protein that binds with high affinity to nascent poly(A) tails, stimulating their extension and controlling their length. In this work we investigated whether PABP2 contributes to the targeting of poly(A) RNA to the speckles. The results show that localization of PABP2 in speckles is independent of import of the protein into the nucleus. Inhibition of transcription or poly(A) synthesis at the end of mitosis does not affect nuclear import of PABP2 but prevents its localization to speckles. Furthermore, PABP2 mutants with decreased ability to bind to poly(A) fail to localize to speckles. Taken together the results show that PABP2 localizes to the nuclear speckles as a consequence of its binding to poly(A) RNA, contrasting to splicing factors which assemble into speckles in the absence of newly synthesized transcripts.
