Protein

Protein S100-A1

Gene

S100a1

Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

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 (By similarity).By similarity

Interactioni

Subunit structurei

Dimer of either two alpha chains, or two beta chains, or one alpha and one beta chain. Also forms heterodimers with S100P. Interacts with AGER and CAPZA1. Interacts with FKBP4. Interacts with RYR1 and RYR2. Interacts with CACYBP in a calcium-dependent manner. Interacts with PPP5C (via TPR repeats); the interaction is calcium-dependent and modulates PPP5C activity (By similarity).By similarity
