Exonuclease-Endonuclease-Phosphatase (EEP) domain superfamily; This large superfamily includes the catalytic domain (exonuclease/endonuclease/phosphatase or EEP domain) of a diverse set of proteins including the ExoIII family of apurinic/apyrimidinic (AP) endonucleases, inositol polyphosphate 5-phosphatases (INPP5), neutral sphingomyelinases (nSMases), deadenylases (such as the vertebrate circadian-clock regulated nocturnin), bacterial cytolethal distending toxin B (CdtB), deoxyribonuclease 1 (DNase1), the endonuclease domain of the non-LTR retrotransposon LINE-1, and related domains. These diverse enzymes share a common catalytic mechanism of cleaving phosphodiester bonds; their substrates range from nucleic acids to phospholipids and perhaps proteins.

C-terminal deadenylase domain of CCR4 and related domains; This subfamily contains the C-terminal catalytic domain of the deadenylases, Saccharomyces cerevisiae Ccr4p and two vertebrate homologs (CCR4a and CCR4b), and related domains. CCR4 belongs to the large EEP (exonuclease/endonuclease/phosphatase) superfamily that contains functionally diverse enzymes that share a common catalytic mechanism of cleaving phosphodiester bonds. CCR4 is the major deadenylase subunit of the CCR4-NOT transcription complex, which contains two deadenylase subunits and several noncatalytic subunits. The other deadenylase subunit, Caf1 (called Pop2 in yeast), is a DEDD-type protein and does not belong in this superfamily. Saccharomyces cerevisiae CCR4 (or Ccr4p) is a 3'-5' poly(A) RNA and ssDNA exonuclease. It is the catalytic subunit of the yeast mRNA deadenylase (Ccr4p/Pop2p/Not complex). This complex participates in various ways in mRNA metabolism, including transcription initiation and elongation, and mRNA degradation. Ccr4p degrades both poly(A) and single-stranded DNA. There are two vertebrate homologs of Ccr4p, CCR4a (also called CCR4-NOT transcription complex subunit 6 or CNOT6) and CCR4b (also called CNOT6-like or CNOT6L), which independently associate with other components to form distinct CCR4-NOT multisubunit complexes. The nuclease domain of CNOT6 and CNOT6L exhibits Mg2+-dependent deadenylase activity, with specificity for poly (A) RNA as substrate. CCR4a is a component of P-bodies and is necessary for foci formation. CCR4b regulates p27/Kip1 mRNA levels, thereby influencing cell cycle progression. They both contribute to the prevention of cell death by regulating insulin-like growth factor-binding protein 5.

CCR4a is a component of P-bodies and is necessary for foci formation of various P-body components. It also plays a role in cellular responses to DNA damage, by regulating Chk2 activity.

C-terminal deadenylase domain of nocturnin and related domains; This subfamily contains the C-terminal catalytic domain of the deadenylase, nocturnin, and related domains. Nocturnin is a poly(A)-specific 3' exonuclease that specifically degrades the 3' poly(A) tail of RNA in a process known as deadenylation. This nuclease activity is manganese dependent. Nocturnin is expressed in the cytoplasm of Xenopus laevis retinal photoreceptor cells in a rhythmic fashion, and it has been proposed that it participates in posttranscriptional regulation of the circadian clock or its outputs, and that the mRNA target(s) of this deadenylase are circadian clock-related. In mouse, the nocturnin gene, mNoc, is expressed in a circadian pattern in a range of tissues including retina, spleen, heart, kidney, and liver. It is highly expressed in bone-marrow stromal cells, adipocytes and hepatocytes. In mammals, nocturnin plays a role in regulating mesenchymal stem-cell lineage allocation, perhaps through regulating PPAR-gamma (peroxisome proliferator-activated receptor-gamma) nuclear translocation. This subfamily belongs to the large EEP (exonuclease/endonuclease/phosphatase) superfamily that contains functionally diverse enzymes that share a common catalytic mechanism of cleaving phosphodiester bonds.
