CCR4-NOT transcription complex subunit 8 (CNOT8), human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 1-292aa. Protein Length: Full Length. Tag Info: N-terminal GST-tagged. Target Protein Sequence: MPAALVENSQ VICEVWASNL EEEMRKIREI VLSYSYIAMD TEFPGVVVRP IGEFRSSIDY QYQLLRCNVD LLKIIQLGLT FTNEKGEYPS GINTWQFNFK FNLTEDMYSQ DSIDLLANSG LQFQKHEEEG IDTLHFAELL MTSGVVLCDN VKWLSFHSGY DFGYMVKLLT DSRLPEEEHE FFHILNLFFP SIYDVKYLMK SCKNLKGGLQ EVADQLDLQR IGRQHQAGSD SLLTGMAFFR MKELFFEDSI DDAKYCGRLY GLGTGVAQKQ NEDVDSAQEK MSILAIINNM QQ. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. 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. Storage: 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. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: 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.
