Protein AATF (AATF), partial, human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 6-294aa. Protein Length: Partial. Tag Info: N-terminal GST-tagged. Target Protein Sequence: PLALQLEQLL NPRPSEADPE ADPEEATAAR VIDRFDEGED GEGDFLVVGS IRKLASASLL DTDKRYCGKT TSRKAWNEDH WEQTLPGSSD EEISDEEGSG DEDSEGLGLE EYDEDDLGAA EEQECGDHRE SKKSRSHSAK TPGFSVQSIS DFEKFTKGMD DLGSSEEEED EESGMEEGDD AEDSQGESEE DRAGDRNSED DGVVMTFSSV KVSEEVEKGR AVKNQIALWD QLLEGRIKLQ KALLTTNQLP QPDVFPLFKD KGGPEFSSAL KNSHKALKAL LRSLVGLQE. 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: May function as a general inhibitor of the histone deacetylase HDAC1. Binding to the pocket region of RB1 may displace HDAC1 from RB1/E2F complexes, leading to activation of E2F target genes and cell cycle progression. Conversely, displacent of HDAC1 from SP1 bound to the CDKN1A promoter leads to increased expression of this CDK inhibitor and blocks cell cycle progression. Also antagonizes PAWR mediated induction of aberrant amyloid peptide production in Alzheimer disease (presenile and senile dentia), although the molecular basis for this phenomenon has not been described to date.
