Lymphokine-activated killer T-cell-originated protein kinase (PBK), human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 1-322aa. Protein Length: Full Length. Tag Info: N-terminal 10xHis-tagged. Target Protein Sequence: MEGISNFKTP SKLSEKKKSV LCSTPTINIP ASPFMQKLGF GTGVNVYLMK RSPRGLSHSP WAVKKINPIC NDHYRSVYQK RLMDEAKILK SLHHPNIVGY RAFTEANDGS LCLAMEYGGE KSLNDLIEER YKASQDPFPA AIILKVALNM ARGLKYLHQE KKLLHGDIKS SNVVIKGDFE TIKICDVGVS LPLDENMTVT DPEACYIGTE PWKPKEAVEE NGVITDKADI FAFGLTLWEM MTLSIPHINL SNDDDDEDKT FDESDFDDEA YYAALGTRPP INMEELDESY QKVIELFSVC TNEDPKDRPS AAHIVEALET DV. 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: Phosphorylates MAP kinase p38. Seems to be active only in mitosis. May also play a role in the activation of lymphoid cells. When phosphorylated, forms a complex with TP53, leading to TP53 destabilization and attenuation of G2/M checkpoint during doxorubicin-induced DNA damage.
