CC -!- FUNCTION: Has 3'-5' poly(A) exoribonuclease activity for synthetic
CC poly(A) RNA substrate. Catalytic component of the CCR4-NOT complex
CC which is one of the major cellular mRNA deadenylases and is linked to
CC various cellular processes including bulk mRNA degradation, miRNA-
CC mediated repression, translational repression during translational
CC initiation and general transcription regulation. During miRNA-mediated
CC repression the complex seems also to act as translational repressor
CC during translational initiation. Additional complex functions may be a
CC consequence of its influence on mRNA expression.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Exonucleolytic cleavage of poly(A) to 5'-AMP.; EC=3.1.13.4;
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Evidence={ECO:0000250};
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC Name=Co(2+); Xref=ChEBI:CHEBI:48828; Evidence={ECO:0000250};
CC Note=Binds 2 divalent metal cations per subunit with RNAase activity
CC being higher in presence of Mn(2+) than of Mg(2+) or Co(2+).
CC {ECO:0000250};
CC -!- SUBUNIT: Component of the CCR4-NOT complex.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}. Cytoplasm {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the CAF1 family. {ECO:0000305}.
