Description
Transcription termination and mRNA export from the nucleus are closely regulated and coordinated processes. Nuclear export factors are recruited to actively transcribed genes through their interactions with protein complexes associated with transcription and co-transcriptional pre-mRNA processing. We determine a new role for the kinase WNK1 in the cross-talk of transcription termination and mRNA export. WNK1 was previously attributed a cytoplasmic role as a regulator of ion transport. However, we now show a nuclear function for this kinase where it is required for efficient mRNA export along with the transcription termination factor PCF11. Finally, we identify the phosphorylation of the CID domain of PCF11 as an important step for the release of the mRNA from the transcription locus, thus allowing efficient mRNA export to the cytoplasm. Overall design: RNA from cytoplasmic and nuclear extracts of HeLa cells was obtained, upon depletion of WNK1 kinase or from control cells. Upon pA selection, libraries were generated and sequenced. A duplicate experiment was performed for each sample.

Description
It is known that CBFB-MYH11, the fusion gene generated by inversion of chromosome 16 in human acute myeloid leukemia, is causative for oncogenic transformation. However, the mechanism by which CBFB-MYH11 initiates leukemogenesis is not clear. Previously published reports showed that CBFB-MYH11 dominantly inhibits RUNX1 and CBFB, and such inhibition has been suggested as the mechanism for leukemogenesis. However, knockin mice expressing Cbfb-MYH11 (Cbfb+/MYH11) showed defects in primitive hematopoiesis not seen in Cbfb null (Cbfb-/-) embryos indicating that Cbfb-MYH11 has repression independent activities as well.

Description
The C-terminus of CBF-SMMHC, the fusion protein produced by a chromosome 16 inversion in acute myeloid leukemia subtype M4Eo, contains domains for self-mulimerization and transcriptional repression, both of which have been proposed to be important for leukemogenesis by CBF-SMMHC. To test the role of the fusion protein's C-terminus in vivo, we generated knock-in mice expressing a C-terminally truncated CBF-SMMHC (CBF-SMMHCC95). Embryos with a single copy of CBF-SMMHCDC95 were viable and showed no defects in hematopoiesis, while embryos homozygous for the CBF-SMMHCC95 allele had hematopoietic defects and died in mid-gestation, similar to embryos with a single-copy of the full-length CBF-SMMHCC95.
Publication Title
The C-terminus of CBFβ-SMMHC is required to induce embryonic hematopoietic defects and leukemogenesis.

Description
The pervasive nature of RNA polymerase II (Pol II) transcription requires efficient termination. A key player in this process is the cleavage and polyadenylation (CPA) factor PCF11, which directly binds to the Pol II C-terminal domain and dismantles elongating Pol II from DNA in vitro. We demonstrate that PCF11-mediated termination is essential for vertebrate development. A range of genomic analyses, including: mNET-seq, 3' mRNA-seq, chromatin RNA-seq and ChIP-seq, reveals that PCF11 enhances transcription termination and stimulates early polyadenylation genome-wide. PCF11 binds preferentially between closely spaced genes, where it prevents transcriptional interference and downstream gene silencing. Notably, PCF11 is sub-stoichiometric to the CPA complex. Low levels of PCF11 are maintained by an auto-regulatory mechanism involving premature termination of its own transcript, and are important for normal development. Both in human cell culture and during zebrafish development, PCF11 selectively attenuates the expression of other transcriptional regulators by premature CPA and termination. Overall design: Semi-nascent transcriptome measured by chromatin-bound RNA-seq in HeLa cells. Control and PCF11 knock-down (2 biological replicates) and control and PCF11 PAS1 deletion (4 biological replicates).

Overall design: 3' mRNA-seq in individual zebrafish embryo heads. Two types of mutants: zPCF11 null and zPCF11 with deletion of PAS1. Wild-type (wt, +/+), heterozygous (het, +/-) and homozygous mutant (hom, -/-) embryos were analyzed. Wild-type and heterozygous animals were phenotypically indistinguishable.
