Form
Liquid or Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
Buffer
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time
Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Function
Has 3'-5' poly(A) exoribonuclease activity for synthetic poly(A) RNA substrate. Its function seems to be partially redundant with that of CNOT7. Catalytic component of the CCR4-NOT complex which is linked to various cellular processes including bulk mRNA degradation, miRNA-mediated repression, translational repression during translational initiation and general transcription regulation. During miRNA-mediated repression the complex seems also to act as translational repressor during translational initiation. Additional complex functions may be a consequence of its influence on mRNA expression. Associates with members of the BTG family such as TOB1 and BTG2 and is required for their anti-proliferative activity.
Gene References into Functions
  1. These results indicate that Caf1 and Ccr4 cooperate in mRNA deadenylation and suggest that the enzyme activities of Caf1 and Ccr4 are regulated via allosteric interactions within the nuclease module. PMID: 25944446
  2. The loss of CAF-1 p48 subunit causes a strong defect in packaging DNA into nucleosomes. PMID: 24036545
  3. show that SMG7 binds directly to POP2, a catalytic subunit of the CCR4-NOT deadenylase complex, and elicits deadenylation-dependent decapping and 5'-to-3' decay of NMD targets PMID: 24115769
  4. The anti-proliferative activity of BTG/TOB proteins is mediated via the Caf1a (CNOT7) and Caf1b (CNOT8) deadenylase subunits of the Ccr4-not complex. PMID: 23236473
  5. The NOT1 MIF4G domain binds CAF1 through a pre-formed interface and leaves the CAF1 catalytic site fully accessible to RNA substrates. PMID: 22977175
  6. N-terminus played a role in modulating hCaf1 activity, stability and aggregation PMID: 22683897
  7. Together, these results indicate that Tob mediates the recruitment of Caf1 to the target of CPEB3 and elicits deadenylation and decay of the mRNA. PMID: 21336257
  8. Tob interactions with Caf1 and a C-terminal domain of PABPC1 PMID: 20595394
  9. CCR4-NOT is the deadenylase that removes poly(A) from messages destabilized by miRNAs in human cells. PMID: 20065043
  10. Cellular POP2 protein binds to central adaptor protein ASC and pathogen recognition receptor PAN1, blocking formation of cryopyrin and PAN1-containing inflammasomes, activation of caspase-1, and subsequent processing of bioactive interleukin-1 beta. PMID: 17178784
  11. Data show that Ccr4-Not function in RNA splicing and nuclear export, and that CNOT8 binds CNOT6 in yeast two-hybrid assays. PMID: 19558367
  12. Data show that efficient cell proliferation requires both CNOT7 and CNOT8, although combined knockdown of both subunits further reduces cell proliferation indicating partial redundancy between these proteins. PMID: 19605561
