LOI1 Pentatricopeptide repeat (PPR) superfamily protein [Arabidopsis thaliana (thale cress)] - Gene

Summary

Go to the top of the page Help

Official Symbol: LOI1
Official Full Name: Pentatricopeptide repeat (PPR) superfamily protein
Primary source: TAIR:AT4G14850
Locus tag: AT4G14850
See related: Araport:AT4G14850
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Arabidopsis thaliana (ecotype: Columbia)
Lineage: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis
Also known as: DL3465W; FCAALL.335; lovastatin insensitive 1; MEF11; mitochondrial RNA editing factor 11
Summary: Encodes a pentatricopeptide (PPR) protein that binds single-stranded RNA. The N-terminal portion of the protein can localize to the mitochondria. Mutations in this gene make plants less sensitive to inhibitors of the MEP and MVA pathways of isoprenoid biosynthesis and increase the activity of HMG CoA reductase.

A restorer-of-fertility-like pentatricopeptide repeat protein promotes cytoplasmic male sterility in Arabidopsis thaliana.
Title: A restorer-of-fertility-like pentatricopeptide repeat protein promotes cytoplasmic male sterility in Arabidopsis thaliana.
he upstream sequences of the BLX-targeted editing sites are not conserved, suggesting that BLX serves as a novel and major mitochondrial editing factor (MEF) via a new non-RNA-interacting manner. This finding provides new insights into how a DYW-type PPR protein with fewer PPR motifs regulates RNA editing in plants.
Title: Novel DYW-type pentatricopeptide repeat (PPR) protein BLX controls mitochondrial RNA editing and splicing essential for early seed development of Arabidopsis.
These observations suggest that the enzymatic activity or its recruitment is not compromised by the alteration of the C-terminus of MEF11.
Title: A truncated MEF11 protein shows site-specific effects on mitochondrial RNA editing.
MEF11 is a nuclear encoded gene which is involved in RNA editing of the three sites cox3-422, nad4-124 and ccb203-344 in Arabidopsis thaliana mitochondria. [MEF11]
Title: The PPR protein encoded by the LOVASTATIN INSENSITIVE 1 gene is involved in RNA editing at three sites in mitochondria of Arabidopsis thaliana.
Identification of RNA editing factor MEF11 as the loi1 gene product
Title: The PPR protein encoded by the LOVASTATIN INSENSITIVE 1 gene is involved in RNA editing at three sites in mitochondria of Arabidopsis thaliana.
report that LOI1 is an essential factor for RNA editing of three mitochondrial genes, nad4, ccb203 and cox3.
Title: The mitochondrial PPR protein LOVASTATIN INSENSITIVE 1 plays regulatory roles in cytosolic and plastidial isoprenoid biosynthesis through RNA editing.
