Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 1-445aa. Protein Length: Full Length. Tag Info: N-terminal GST-tagged. Target Protein Sequence: MAEYDLTTRI AHFLDRHLVF PLLEFLSVKE IYNEKELLQG KLDLLSDTNM VDFAMDVYKN LYSDDIPHAL REKRTTVVAQ LKQLQAETEP IVKMFEDPET TRQMQSTRDG RMLFDYLADK HGFRQEYLDT LYRYAKFQYE CGNYSGAAEY LYFFRVLVPA TDRNALSSLW GKLASEILMQ NWDAAMEDLT RLKETIDNNS VSSPLQSLQQ RTWLIHWSLF VFFNHPKGRD NIIDLFLYQP QYLNAIQTMC PHILRYLTTA VITNKDVRKR RQVLKDLVKV IQQESYTYKD PITEFVECLY VNFDFDGAQK KLRECESVLV NDFFLVACLE DFIENARLFI FETFCRIHQC ISINMLADKL NMTPEEAERW IVNLIRNARL DAKIDSKLGH VVMGNNAVSP YQQVIEKTKS LSFRSQMLAM NIEKKLNQNS RSEAPNWATQ DSGFY. 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: omponent of the eukaryotic translation initiation factor 3 (eIF-3) complex, which is required for several steps in the initiation of protein synthesis . The eIF-3 complex associates with the 40S ribosome and facilitates the recruitment of eIF-1, eIF-1A, eIF-2:GTP:methionyl-tRNAi and eIF-5 to form the 43S pre-initiation complex (43S PIC). The eIF-3 complex stimulates mRNA recruitment to the 43S PIC and scanning of the mRNA for AUG recognition. The eIF-3 complex is also required for disassembly and recycling of post-termination ribosomal complexes and subsequently prevents premature joining of the 40S and 60S ribosomal subunits prior to initiation . The eIF-3 complex specifically targets and initiates translation of a subset of mRNAs involved in cell proliferation, including cell cycling, differentiation and apoptosis, and uses different modes of RNA stem-loop binding to exert either translational activation or repression . Required for nonsense-mediated mRNA decay (NMD), may act in conjunction with UPF2 to divert mRNAs from translation to the NMD pathway . May interact with MCM7 and EPAS1 and regulate the proteasome-mediated degradation of these proteins.
