Gene Gene information from NCBI Gene database.
Entrez ID 5073
Gene name Poly(A)-specific ribonuclease
Gene symbol PARN
Synonyms (NCBI Gene)
DANDKCB6PFBMFT4
Chromosome 16
Chromosome location 16p13.12
Summary The protein encoded by this gene is a 3`-exoribonuclease, with similarity to the RNase D family of 3`-exonucleases. It prefers poly(A) as the substrate, hence, efficiently degrades poly(A) tails of mRNAs. Exonucleolytic degradation of the poly(A) tail is

Protein name Poly(A)-specific ribonuclease PARN (EC 3.1.13.4) (Deadenylating nuclease) (Deadenylation nuclease) (Polyadenylate-specific ribonuclease)
Protein function 3'-exoribonuclease that has a preference for poly(A) tails of mRNAs, thereby efficiently degrading poly(A) tails. Exonucleolytic degradation of the poly(A) tail is often the first step in the decay of eukaryotic mRNAs and is also used to silence
