Protein

Polyribonucleotide nucleotidyltransferase 2, mitochondrial

Gene

PNP2

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at transcript leveli

Functioni

Involved in the 3'-end maturation of mitochondrial mRNAs, rRNAs and tRNAs. Functions as a poly(A) mRNA 3'-5' degrading phosphorylase and is required for the degradation of highly expressed transcripts of non-coding regions.2 Publications

Catalytic activityi

RNA(n+1) + phosphate = RNA(n) + a nucleoside diphosphate.
