Tribbles homolog 3 (Trib3), mouse, recombinant

Organism: Mus musculus (Mouse). Source: E.coli. Expression Region: 1-354aa. Protein Length: Full Length. Tag Info: N-terminal 10xHis-tagged and C-terminal Myc-tagged. Target Protein Sequence: MRATPLAASA DVSCRKKPLE FDDNIDAKCP VLKRVRDEPE PGPLPSLLPP SPPPASDLSP AVAPATRLGP YILLEREQGS CSYRALHCPT GTEYTCKVYP ASEAQAVLAP YARLPTHQHV ARPTEVLLGS RLLYIFFTKT HGDLHSLVRS RRGIPESEAA GLFRQMASAV AHCHKHGLVL RDLKLRRFVF SNCERTKLVL ENLEDACVMT GSDDSLWDKH ACPAYVGPEI LSSRPSYSGK AADVWSLGVA LFTMLAGRYP FHDSEPVLLF GKIRRGTFAL PEGLSAPARC LIRCLLRKEP SERLVALGIL LHPWLREDHG RVSPPQSDRR EMDQVVPDGP QLEEAEEGEV GLYG. Purity: Greater than 85% 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: Inactive protein kinase which acts as a regulator of the integrated stress response (ISR), a process for adaptation to various stress . Inhibits the transcriptional activity of DDIT3/CHOP and is involved in DDIT3/CHOP-dependent cell death during ER stress . May play a role in programmed neuronal cell death but does not appear to affect non-neuronal cells . Acts as a negative feedback regulator of the ATF4-dependent transcription during the ISR: while TRIB3 expression is promoted by ATF4, TRIB3 protein interacts with ATF4 and inhibits ATF4 transcription activity . Disrupts insulin signaling by binding directly to Akt kinases and blocking their activation . May bind directly to and mask the 'Thr-308' phosphorylation site in AKT1 . Interacts with the NF-kappa-B transactivator p65 RELA and inhibits its phosphorylation and thus its transcriptional activation activity . Interacts with MAPK kinases and regulates activation of MAP kinases . Can inhibit APOBEC3A editing of nuclear DNA .
