Biochem/physiol Actions

S100 calcium-binding protein A1 (S100A1) is a protein encoded by the S100A1 gene in humans. It is referred to as S100, S100A and S100-α and belongs to Ca2+-binding S100 protein family. The protein is a homodimer of noncovalently bound subunits. It is a multifunctional regulatory protein involved in a variety of biological processes and closely associated with several human diseases. This gene is expressed in brain and heart tissue, where it plays an important role as a modulator of Ca2+ homeostasis, energy metabolism, neurotransmitter release and contractile performer. Abnormal expression of this protein is associated with neurodegenerative and inflammatory disorders, myopathies and cancer.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.
