Casein kinase I isoform alpha (CSNK1A1), human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 2-337aa. Protein Length: Full Length of Mature Protein. Tag Info: N-terminal 6xHis-tagged. Target Protein Sequence: ASSSGSKAEF IVGGKYKLVR KIGSGSFGDI YLAINITNGE EVAVKLESQK ARHPQLLYES KLYKILQGGV GIPHIRWYGQ EKDYNVLVMD LLGPSLEDLF NFCSRRFTMK TVLMLADQMI SRIEYVHTKN FIHRDIKPDN FLMGIGRHCN KLFLIDFGLA KKYRDNRTRQ HIPYREDKNL TGTARYASIN AHLGIEQSRR DDMESLGYVL MYFNRTSLPW QGLKAATKKQ KYEKISEKKM STPVEVLCKG FPAEFAMYLN YCRGLRFEEA PDYMYLRQLF RILFRTLNHQ YDYTFDWTML KQKAAQQAAS SSGQGQQAQT PTGKQTDKTK SNMKGF. 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: Casein kinases are operationally defined by their preferential utilization of acidic proteins such as caseins as substrates. It can phosphorylate a large number of proteins. Participates in Wnt signaling. Phosphorylates CTNNB1 at 'Ser-45'. May phosphorylate PER1 and PER2. May play a role in segregating chromosomes during mitosis.
