Protein

PAB-dependent poly(A)-specific ribonuclease subunit PAN2

Gene

PAN2

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Catalytic subunit of the poly(A)-nuclease (PAN) deadenylation complex, one of two cytoplasmic mRNA deadenylases involved in mRNA turnover. PAN specifically shortens poly(A) tails of RNA when the poly(A) stretch is bound by poly(A)-binding protein PAB1, which is followed by rapid degradation of the shortened mRNA tails by the CCR4-NOT complex. Deadenylated mRNAs are then degraded by two alternative mechanisms, namely exosome-mediated 3'-5' exonucleolytic degradation, or deadenlyation-dependent mRNA decaping by DCP1-DCP2 and subsequent 5'-3' exonucleolytic degradation by XRN1. May also be involved in post-transcriptional maturation of mRNA poly(A) tails, trimming the tails from their synthesized length to the slightly shorter, apparently messenger-specific length found on newly exported mRNAs. PAN cooperates with protein kinase DUN1 in the regulation of RAD5 mRNA levels and cell survival in response to replicational stress.UniRule annotation8 Publications

Catalytic activityi

Exonucleolytic cleavage of poly(A) to 5'-AMP.UniRule annotation1 Publication

Enzyme regulationi

Positively regulated by the regulatory subunit PAN3. Negatively regulated by PAB1-binding protein PBP1. Inhibited under stress conditions. Inhibition of deadenylation under stress increases mRNA stability, which may be a mechanism to retain the majority of the cytoplasmic pool of mRNAs for later reuse and recovery from stress.UniRule annotation3 Publications
