CC -!- FUNCTION: Catalytic subunit of the poly(A)-nuclease (PAN) deadenylation
CC complex, one of two cytoplasmic mRNA deadenylases involved in mRNA
CC turnover. PAN specifically shortens poly(A) tails of RNA and the
CC activity is stimulated by poly(A)-binding protein PAB1. PAN
CC deadenylation is followed by rapid degradation of the shortened mRNA
CC tails by the CCR4-NOT complex. Deadenylated mRNAs are then degraded by
CC two alternative mechanisms, namely exosome-mediated 3'-5'
CC exonucleolytic degradation, or deadenlyation-dependent mRNA decaping
CC and subsequent 5'-3' exonucleolytic degradation by XRN1. May also be
CC involved in post-transcriptional maturation of mRNA poly(A) tails.
CC {ECO:0000256|HAMAP-Rule:MF_03182}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Exonucleolytic cleavage of poly(A) to 5'-AMP.; EC=3.1.13.4;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_03182};
CC -!- COFACTOR:
CC Name=a divalent metal cation; Xref=ChEBI:CHEBI:60240;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_03182};
CC Note=Binds 2 metal cations per subunit in the catalytic exonuclease
CC domain. {ECO:0000256|HAMAP-Rule:MF_03182};
CC -!- ACTIVITY REGULATION: Positively regulated by the regulatory subunit
CC PAN3. {ECO:0000256|HAMAP-Rule:MF_03182}.
CC -!- SUBUNIT: Forms a heterotrimer with an asymmetric homodimer of the
CC regulatory subunit PAN3 to form the poly(A)-nuclease (PAN)
CC deadenylation complex. {ECO:0000256|HAMAP-Rule:MF_03182}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_03182}.
CC -!- DOMAIN: Contains a pseudo-UCH domain. This ubiquitin C-terminal
CC hydrolase (UCH)-like or ubiquitin specific protease (USP)-like domain
CC is predicted to be catalytically inactive because it lacks the active
CC site catalytic triad characteristic of thiol proteases, with residues
CC at the equivalent structural positions that are incompatible with
CC catalysis, and it cannot bind ubiquitin. It functions as a structural
CC scaffold for intra- and intermolecular interactions in the complex.
CC {ECO:0000256|HAMAP-Rule:MF_03182}.
CC -!- DOMAIN: The linker, or PAN3 interaction domain (PID), between the WD40
CC repeats and the pseudo-UCH domain mediates interaction with PAN3.
CC {ECO:0000256|HAMAP-Rule:MF_03182}.
CC -!- SIMILARITY: Belongs to the peptidase C19 family. PAN2 subfamily.
CC {ECO:0000256|HAMAP-Rule:MF_03182}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_03182}.
