Baculoviral IAP repeat-containing protein 1 (NAIP), partial, human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 60-345aa. Protein Length: Partial. Tag Info: N-terminal 6xHis-SUMO-tagged. Target Protein Sequence: EAKRLKTFVT YEPYSSWIPQ EMAAAGFYFT GVKSGIQCFC CSLILFGAGL TRLPIEDHKR FHPDCGFLLN KDVGNIAKYD IRVKNLKSRL RGGKMRYQEE EARLASFRNW PFYVQGISPC VLSEAGFVFT GKQDTVQCFS CGGCLGNWEE GDDPWKEHAK WFPKCEFLRS KKSSEEITQY IQSYKGFVDI TGEHFVNSWV QRELPMASAY CNDSIFAYEE LRLDSFKDWP RESAVGVAAL AKAGLFYTGI KDIVQCFSCG GCLEKWQEGD DPLDDHTRCF PNCPFL. 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: Anti-apoptotic protein which acts by inhibiting the activities of CASP3, CASP7 and CASP9. Can inhibit the autocleavage of pro-CASP9 and cleavage of pro-CASP3 by CASP9. Capable of inhibiting CASP9 autoproteolysis at 'Asp-315' and decreasing the rate of auto proteolysis at 'Asp-330'. Acts as a mediator of neuronal survival in pathological conditions. Prevents motor-neuron apoptosis induced by a variety of signals. Possible role in the prevention of spinal muscular atrophy that ses to be caused by inappropriate persistence of motor-neuron apoptosis: mutated or deleted forms of NAIP have been found in individuals with severe spinal muscular atrophy.Acts as a sensor component of the NLRC4 inflammasome that specifically recognizes and binds needle protein CprI from pathogenic bacteria C.violaceum. Association of pathogenic bacteria proteins drives in turn drive assbly and activation of the NLRC4 inflammasome, promoting caspase-1 activation, cytokine production and macrophage pyroptosis. The NLRC4 inflammasome is activated as part of the innate immune response to a range of intracellular bacteria such as C.violaceum and L.pneumophila. Reference: Integrity of ATP binding site is essential for effective inhibition of the intrinsic apoptosis pathway by NAIP.Karimpour S., Davoodi J., Ghahremani M.H.Biochem. Biophys. Res.
