Cellular tumor antigen p53 (Tp53), rat, recombinant

Organism: Rattus norvegicus (Rat). Source: E.coli. Expression Region: 1-391aa. Protein Length: Full Length. Tag Info: N-terminal 6xHis-tagged. Target Protein Sequence: MEDSQSDMSI ELPLSQETFS CLWKLLPPDD ILPTTATGSP NSMEDLFLPQ DVAELLEGPE EALQVSAPAA QEPGTEAPAP VAPASATPWP LSSSVPSQKT YQGNYGFHLG FLQSGTAKSV MCTYSISLNK LFCQLAKTCP VQLWVTSTPP PGTRVRAMAI YKKSQHMTEV VRRCPHHERC SDGDGLAPPQ HLIRVEGNPY AEYLDDRQTF RHSVVVPYEP PEVGSDYTTI HYKYMCNSSC MGGMNRRPIL TIITLEDSSG NLLGRDSFEV RVCACPGRDR RTEEENFRKK EEHCPELPPG SAKRALPTST SSSPQQKKKP LDGEYFTLKI RGRERFEMFR ELNEALELKD ARAAEESGDS RAHSSYPKTK KGQSTSRHKK PMIKKVGPDS D. 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: Acts as a tumor suppressor in many tumor types, induces growth arrest or apoptosis depending on the physiological circumstances and cell type. Involved in cell cycle regulation as a trans-activator that acts to negatively regulate cell division by controlling a set of genes required for this process. One of the activated genes is an inhibitor of cyclin-dependent kinases. Apoptosis induction ses to be mediated either by stimulation of BAX and FAS antigen expression, or by repression of Bcl-2 expression. In cooperation with mitochondrial PPIF is involved in activating oxidative stress-induced necrosis, the function is largely independent of transcription. Prevents CDK7 kinase activity when associated to CAK complex in response to DNA damage, thus stopping cell cycle progression. Induces the transcription of long intergenic non-coding RNA p21 (lincRNA-p21) and lincRNA-Mkln1. LincRNA-p21 participates in TP53-dependent transcriptional repression leading to apoptosis and se to have to effect on cell-cycle regulation. Regulates the circadian clock by repressing CLOCK-ARNTL/BMAL1-mediated transcriptional activation of PER2.
