Expression:
P23297 S10A1_HUMAN:

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

Description:
S100A1 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.

Research Backgrounds

Function:

Probably acts as a Ca(2+) signal transducer. In response to an increase in intracellular Ca(2+) levels, binds calcium which triggers a conformational change. This conformational change allows interaction of S1001A with specific target proteins, such as TPR-containing proteins, and the modulation of their activity.

Subcellular Location:

Cytoplasm.

Extracellular region or secreted Cytosol Plasma membrane Cytoskeleton Lysosome Endosome Peroxisome ER Golgi apparatus Nucleus Mitochondrion Manual annotation Automatic computational assertionSubcellular location
Tissue Specificity:

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

Subunit Structure:

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 (By similarity). Interacts with CAPZA1 (By similarity). 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.

Family&Domains:

Belongs to the S-100 family.
