FUNCTION: Ribosome biogenesis factor that coordinates hyperactive transcription and ribogenesis (PubMed:17699751). Involved in nucleolar processing of pre-18S ribosomal RNA. Required for optimal pre-ribosomal RNA transcription by RNA polymerase I (PubMed:17699751). Essential for stem cell pluripotency and embryonic development. In the nucleoplasm, recruited by promoter-associated/nascent transcripts and transcription to active promoters where it facilitates releases of elongation factor P-TEFb and paused RNA polymerase II to allow transcription elongation and maintain high-level expression of its targets genes (By similarity). {ECO:0000250|UniProtKB:Q6ZQL4, ECO:0000269|PubMed:17699751}.
