Ubiquitin is a highly-conserved protein that is widely expressed in eukaryotes (1). Ubiquitin is required for ATP-dependent, nonlysosomal intracellular protein degradation of abnormal and normal proteins with a rapid turnover. A mutant form of ubiquitin, UBB+1,accumulates in the pathological hallmarks of tauopathies, including Alzheimer's disease, polyglutamine diseases, liver disease and muscle disease and serves as an endogenous reporter for proteasomal dysfunction in these diseases. By inhibiting the proteasome machinery, UBB+1 is pathogenic, since it promotes accumulation of cytotoxic misfolded amyloid-beta and phosphorylated-tau (2). Ubiquitin Protein is ideal for investigators involved in Signaling Proteins, Ubiquitin Proteins, Angiogenesis, Apoptosis/Autophagy, Cancer, Cell Cycle, Cellular Stress, Inflammation, Invasion/Metastasis, and Neurobiology research.
Store product at –70°C. For optimal storage, aliquot target into smaller quantities after centrifugation and store at recommended temperature. For most favorable performance, avoid repeated handling and multiple freeze/thaw cycles.
