General annotation (Comments)

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.

Subunit structure

Dimer of either two alpha chains, or two beta chains, or one alpha and one beta chain. Interacts with AGER and CAPZA1 By similarity. Interacts with FKBP4. Ref.5 Ref.6

Subcellular location

Cytoplasm.

Tissue specificity

Highly prevalent in heart. Also found in lesser quantities in skeletal muscle and brain.

Sequence similarities

Belongs to the S-100 family.

Contains 2 EF-hand domains.

Binary interactions
