Calcium uniporter protein, mitochondrial (Mcu), mouse, recombinant

Organism: Mus musculus (Mouse). Source: in vitro E.coli expression system. Expression Region: 50-350aa. Protein Length: Full Length of Mature Protein. Tag Info: N-terminal 10xHis-tagged. Target Protein Sequence: AHQRPASWQS VGAAYCSTVV PSDDVTVVYQ NGLPVISVRL PSRRERCQFT LKPISDSVGV FLRQLQEEDR GIDRVAIYSP DGVRVAASTG IDLLLLDDFK LVINDLTYHV RPPKRDLLSH EDAATLNDVK TLVQQLYTTL CIEQHQLNKE RELVERLEDL KQQLAPLEKV RIEISRKAEK RTTLVLWGGL AYMATQFGIL ARLTWWEYSW DIMEPVTYFI TYGSAMAMYA YFVMTRQEYV YPEARDRQYL LFFHKGAKKS RFDLEKYNQL KDAIAQAEMD LKRLRDPLQV HLPLRQIGEK E. 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: Mitochondrial inner membrane calcium uniporter that mediates calcium uptake into mitochondria. Constitutes the pore-forming and calcium-conducting subunit of the uniporter complex. Activity is regulated by MICU1 and MICU2. At low Ca2+ levels MCU activity is down-regulated by MICU1 and MICU2, at higher Ca2+ levels MICU1 increases MCU activity. Mitochondrial calcium homeostasis plays key roles in cellular physiology and regulates cell bioenergetics, cytoplasmic calcium signals and activation of cell death pathways. Involved in buffering the amplitude of systolic calcium rises in cardiomyocytes . While dispensable for baseline homeostatic cardiac function, acts as a key regulator of short-term mitochondrial calcium loading underlying a 'fight-or-flight' response during acute stress: acts by mediating a rapid increase of mitochondrial calcium in pacemaker cells. Participates in mitochondrial permeability transition during ischemia-reperfusion injury. Regulates glucose-dependent insulin secretion in pancreatic beta-cells by regulating mitochondrial calcium uptake. Mitochondrial calcium uptake in skeletal muscle cells is involved in muscle size in adults. Regulates synaptic vesicle endocytosis kinetics in central nerve terminal. Involved in antigen processing and presentation. Reference: "Integrative genomics identifies MCU as an essential component of the mitochondrial calcium uniporter."
