| + | [[http://www.uniprot.org/uniprot/PAN2_NEUCR PAN2_NEUCR]] 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 pabp-1, 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 and subsequent 5'-3' exonucleolytic degradation by xrn1. May also be involved in post-transcriptional maturation of mRNA poly(A) tails (By similarity). [[http://www.uniprot.org/uniprot/PAN3_NEUCR PAN3_NEUCR]] Regulatory subunit of the poly(A)-nuclease (PAN) deadenylation complex involved in cytoplasmic mRNA turnover. PAN specifically shortens poly(A) tails of RNA when the poly(A) stretch is bound by polyadenylate-binding protein pab-1. Deadenylation of the 3'-tail to a length that is too short to bind pab-1 induces mRNA decay. May also be involved in post-transcriptional maturation of mRNA poly(A) tails. pan-3 acts as a positive regulator for PAN activity, recruiting pan-2 to mRNA via its interaction with pab-1 (By similarity). | ||
