UniprotKB/SwissProt ID: S10A1_HUMAN (P23297)
Gene Name: S100A1
Synonyms: S100A
Organism: Homo sapiens (Human).
Function: Weakly binds calcium but binds zinc very tightly- distinct binding sites with different affinities exist for both ions on each monomer. Physiological concentrations of potassium ion antagonize the binding of both divalent cations, especially affecting high-affinity calcium-binding sites. May mediate calcium-dependent regulation on many physiological processes by interacting with other proteins, such as TPR-containing proteins, and modulating their activity.
