1. Poly(A)-Specific Ribonuclease (PARN)
Abstract : Degradation of the mRNA 3'-end located poly(A) tail is an important step for mRNA decay in mammalian cells. Thus, to understand mRNA decay in detail, it is important to identify the catalytic activities involved in degrading poly(A). READ MORE

2. Allosteric Regulation of mRNA Metabolism : -Mechanisms of Cap-Dependent Regulation of Poly(A)-specific Ribonuclease (PARN)
Abstract : Degradation of mRNA is a highly regulated step important for proper gene expression. Degradation of eukaryotic mRNA is initiated by shortening of the 3’ end located poly(A) tail. Poly(A)-specific ribonuclease (PARN) is an oligomeric enzyme that degrades the poly(A) tail with high processivity. READ MORE

3. Polyadenylation and deadenylation of messenger RNA in eukaryotic cells
Abstract : .... READ MORE

4. Spatial control of mRNA stability in yeast
Abstract : The degradation of mRNA is an important modulator of gene expression and the ultimate fate of messenger mRNA. Important steps in the degradation of mRNA include initial shortening of its poly(A) tail followed by the subsequent removal of the m7G cap. These two processes are linked temporally as well as spatially. READ MORE

5. PARN – The Tail End : Function and mechanisms of specificity and processivity
Abstract : Poly(A)-specific ribonuclease (PARN) is an exoribonuclease that is processive, poly(A) specific and cap-binding. PARN deadenylates the poly(A) tails present on a subset of mRNAs and non-coding RNAs, including among others certain snoRNAs, miRNAs and precursor rRNAs. READ MORE
