abstract：:Coupling between transcription and RNA processing is a key gene regulatory mechanism. Here we use chromatin immunoprecipitation to detect transcription-dependent accumulation of the precursor mRNA (pre-mRNA) splicing factors hnRNP A1, U2AF65 and U1 and U5 snRNPs on the intron-containing human FOS gene. These factors w...
