Kpaf3 mitochondrial editing
Webmitochondria, the RNA editing of “structural” RNAs, the small subunit ribosomal RNAs (SSU rRNAs), was also observed (Mahendran et al., 1994; Barth et al., 1999). Although the function of RNA editing in these “structural” rRNAs is still unclear, some evidence has indicated that these editing events may be required for the formation of WebMITOCHONDRIAL EDITING FACTOR 3: Description: Encodes a sequence-specific RNA editing factor involved in editing of the atp4-89 site in plant mitochondria.

WebIt follows that KPAF3-bound pre-edited mRNA is protected against 3′–5′ degradation and remains stable while losing A-tail upon KPAP1 knockdown5,8. It has been suggested that KPAF3 displacement by the editing sequence changes would leave the partially edited transcript reliant on the short A-tail as an critical stability determinant5. Web1 nov. 2009 · This work characterized a nuclear-encoded gene that is involved in RNA editing of three specific sites in different mitochondrial mRNAs in Arabidopsis thaliana, editing sites rps4-956, nad7-963, and nad2-1160, and identified this first factor identified for RNA editing in plant mitochondria.
WebIn vitro, KPAF3 stimulates KPAP1 activity and inhibits mRNA uridylation by RET1 TUTase. Our findings indicate that KPAF3 selectively directs pre-mRNA toward adenylation rather … Web8 jul. 2024 · The researchers called their tool a DddA-derived cytosine base editor (DdCBE). The team tested DdCBE on five genes in the mitochondrial genome in human cells and found that DdCBE installed precise base edits in up to 50 percent of the mitochondrial DNA. They focused on the gene ND4, which encodes a subunit of the …
WebIn mitochondrial extracts, 3′ adenylation reportedly influences degradation kinetics of synthetic edited and pre‐edited mRNAs. We have identified and characterized a mitochondrial poly(A) polymerase, termed KPAP1, and determined major polypeptides in the polyadenylation complex.

Webeliminates RNA editing competence at the three identified target sites cox3-422, nad4-124 and ccb203-344. Surprisingly, the T-DNA insertion in the DYW-domain in line mef11-2 completely blocks RNA editing at just the two sites cox3-422 and A truncated MEF11 protein shows site-specific effects on mitochondrial RNA editing
