AbstractHeterogeneous ribonucleoproteins (hnRNPs) are RNA binding molecules that are involved in key processes such as RNA splicing and transcription. One such hnRNP protein, hnRNP L, regulates alternative splicing (AS) by binding to pre-mRNA transcripts. However, it is unclear what factors contribute to hnRNP L-regulated AS events. Using proteomic approaches, we identified several key factors that co-purify with hnRNP L. We demonstrate that one such factor, the histone methyltransferase SETD2, specifically interacts with hnRNP L in vitro and in vivo. This interaction occurs through a previously uncharacterized domain in SETD2, the SETD2-hnRNP Interaction (SHI) domain, the deletion of which, leads to a reduced H3K36me3 deposition. Functionally, SETD2 regulates a subset of hnRNP L-targeted AS events. Our findings demonstrate that SETD2, by interacting with Pol II as well as hnRNP L, can mediate the crosstalk between the transcription and the splicing machinery.

Abstract Key message RNA PROCESSING FACTORs 1 AND 8 (RPF1 and RPF8), both restorer of fertility like pentatricopeptide repeat proteins, are required for processing of dicistronic nad4L-atp4 and nad3-rps12 transcripts in Arabidopsis mitochondria. Abstract In mitochondria of Arabidopsis thaliana (Arabidopsis), the 5′ termini of many RNAs are generated on the post-transcriptional level. This process is still poorly understood in terms of both the underlying mechanism as well as proteins required. Our studies now link the generation of polymorphic 5′ extremities of the dicistronic nad3-rps12 and nad4L-atp4 transcripts to the function of the P-type pentatricopeptide repeat proteins RNA PROCESSING FACTORs 8 (RPF8) and 1 (RPF1). RPF8 is required to generate the nad3-rps12 -141 5′ end in ecotype Van-0 whereas the RPF8 allele in Col has no function in the generation of any 5′ terminus of this transcript. This observation strongly suggests the involvement of an additional factor in the generation of the -229 5′ end of nad3-rps12 transcripts in Col. RPF1, previously found to be necessary for the generation of the -228 5′ end of the major 1538 nucleotide-long nad4 mRNAs, is also important for the formation of nad4L-atp4 transcripts with a 5′ end at position -318 in Col. Many Arabidopsis ecotypes contain inactive RPF1 alleles resulting in the accumulation of various low abundant nad4L-atp4 RNAs which might represent precursor and/or degradation products. Some of these ecotypes accumulate major, but slightly smaller RNA species. The introduction of RPF1 into these lines not only establishes the formation of the major nad4L-atp4 dicistronic mRNA with the -318 5′ terminus, the presence of this gene also suppresses the accumulation of most alternative nad4L-atp4 RNAs. Beside RPF1, several other factors contribute to nad4L-atp4 transcript formation.
