摘要: Mutations in the RNA-binding protein FUS (fused sarcoma)/TLS have been shown to cause neurodegenerative disease amyotrophic lateral sclerosis (ALS), but normal role of is incompletely understood. We found that binds C-terminal domain (CTD) RNA polymerase II (RNAP2) and prevents inappropriate hyperphosphorylation Ser2 RNAP2 CTD at thousands human genes. The loss leads accumulation transcription start site a shift mRNA isoform expression toward early polyadenylation sites. Thus, addition its alternative splicing, has general function orchestrating phosphorylation during transcription.
