Ligands: CA, TRS Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function [S10A1_HUMAN] 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. See Also S100 protein
