UniProt functional annotation for P31384

UniProt code: P31384.

Organism: Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast).
Taxonomy: Eukaryota; Fungi; Dikarya; Ascomycota; Saccharomycotina; Saccharomycetes; Saccharomycetales; Saccharomycetaceae; Saccharomyces.
 
Function: Acts as catalytic component of the CCR4-NOT core complex, which in the nucleus seems to be a general transcription factor, and in the cytoplasm the major mRNA deadenylase involved in mRNA turnover. CCR4 has 3'-5' RNase activity with a strong preference for polyadenylated substrates and also low exonuclease activity towards single-stranded DNA. Discovered because of its role in the control of ADH2 gene expression. It is required for the expression of genes involved in non-fermentative growth and it mediates or is required for the action of the SPT6 and SPT10 genes. {ECO:0000269|PubMed:11239395, ECO:0000269|PubMed:11889047, ECO:0000269|PubMed:11889048, ECO:0000269|PubMed:9463387}.
 
Catalytic activity: Reaction=Exonucleolytic cleavage of poly(A) to 5'-AMP.; EC=3.1.13.4;
Cofactor: Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
Subunit: Subunit of the 1.0 MDa CCR4-NOT core complex that contains CCR4, CAF1, NOT1, NOT2, NOT3, NOT4, NOT5, CAF40 and CAF130. In the complex interacts with NOT1. The core complex probably is part of a less characterized 1.9 MDa CCR4-NOT complex. {ECO:0000269|PubMed:10490603, ECO:0000269|PubMed:11733989, ECO:0000269|PubMed:9463387}.
Subcellular location: Cytoplasm {ECO:0000269|PubMed:11239395}. Nucleus {ECO:0000269|PubMed:11239395}.
Domain: The 169 C-terminal residues are important for deadenylase activity.
Miscellaneous: Present with 2780 molecules/cell in log phase SD medium. {ECO:0000269|PubMed:14562106}.
Similarity: Belongs to the CCR4/nocturin family. {ECO:0000305}.
