Description

  • Product name

    Recombinant human Superoxide Dismutase 1 protein
    See all Superoxide Dismutase 1 proteins and peptides
  • Biological activity

    Specific activity is > 90 units/mg, in which one unit will inhibit the rate of reduction of cytochrome c by 50% in a coupled system, using xanthine and Xanthine oxidase at pH 7.8 at 25°C in a 1.5 ml reaction volume.

    Activity Assay

    1. Prepare a 1.5 ml reaction mix into a suitable container and pre-chill on ice before use: The final concentrations are 50mM potassium phosphate, 0.1mM ethylendiaminetetraacetic acid, 0.01mM cytochrome C 0.05mM xanthine, 0.005 units xanthine oxidase.
    2. Equilibrate to 25°C and monitor at A550nm until the value is constant using a spectrophotometer.
    3. Add 50 ul of recombinant SOD protein in various concentrations (0.5ug, 1ug) in assay buffer.
    4. Mix by inversion and record the increase at A550nm for 5 minutes.

  • Function

    Destroys radicals which are normally produced within the cells and which are toxic to biological systems.
  • Involvement in disease

    Defects in SOD1 are the cause of amyotrophic lateral sclerosis type 1 (ALS1) [MIM:105400]. ALS1 is a familial form of amyotrophic lateral sclerosis, a neurodegenerative disorder affecting upper and lower motor neurons and resulting in fatal paralysis. Sensory abnormalities are absent. Death usually occurs within 2 to 5 years. The etiology of amyotrophic lateral sclerosis is likely to be multifactorial, involving both genetic and environmental factors. The disease is inherited in 5-10% of cases leading to familial forms.
  • Sequence similarities

    Belongs to the Cu-Zn superoxide dismutase family.
  • Post-translational
    modifications

    Unlike wild-type protein, the pathogenic variants ALS1 Arg-38, Arg-47, Arg-86 and Ala-94 are polyubiquitinated by RNF19A leading to their proteasomal degradation. The pathogenic variants ALS1 Arg-86 and Ala-94 are ubiquitinated by MARCH5 leading to their proteasomal degradation.
    The ditryptophan cross-link at Trp-33 is reponsible for the non-disulfide-linked homodimerization. Such modification might only occur in extreme conditions and additional experimental evidence is required.
  • Cellular localization

    Cytoplasm. The pathogenic variants ALS1 Arg-86 and Ala-94 gradually aggregates and accumulates in mitochondria.
  • Information by UniProt
