Summaries for S100A1 Gene

Entrez Gene Summary for S100A1 Gene

  • The protein encoded by this gene is a member of the S100 family of proteins containing 2 EF-hand calcium-binding motifs. S100 proteins are localized in the cytoplasm and/or nucleus of a wide range of cells, and involved in the regulation of a number of cellular processes such as cell cycle progression and differentiation. S100 genes include at least 13 members which are located as a cluster on chromosome 1q21. This protein may function in stimulation of Ca2+-induced Ca2+ release, inhibition of microtubule assembly, and inhibition of protein kinase C-mediated phosphorylation. Reduced expression of this protein has been implicated in cardiomyopathies. [provided by RefSeq, Jul 2008]

GeneCards Summary for S100A1 Gene

S100A1 (S100 Calcium Binding Protein A1) is a Protein Coding gene. Diseases associated with S100A1 include Myoepithelioma and Malignant Peripheral Nerve Sheath Tumor. Among its related pathways are Innate Immune System and Activated TLR4 signalling. Gene Ontology (GO) annotations related to this gene include calcium ion binding and identical protein binding. An important paralog of this gene is S100Z.

UniProtKB/Swiss-Prot for S100A1 Gene

  • Probably acts as a Ca(2+) signal transducer (PubMed:22399290). In response to an increase in intracellular Ca(2+) levels, binds calcium which triggers a conformational change (PubMed:23351007). This conformational change allows interaction of S1001A with specific target proteins, such as TPR-containing proteins, and the modulation of their activity (PubMed:22399290).

    • Dimer of either two alpha chains, or two beta chains, or one alpha and one beta chain (PubMed:21296671). Also forms heterodimers with S100P (PubMed:15171681). Interacts with AGER (By similarity). Intreacts with CAPZA1 (By similarity). Interacts with FKBP4 (PubMed:20188096). Interacts with RYR1 and RYR2 (PubMed:18650434). Interacts with CACYBP in a calcium-dependent manner (PubMed:12042313). Interacts with PPP5C (via TPR repeats); the interaction is calcium-dependent and modulates PPP5C activity (PubMed:22399290).
    • Able to bind zinc in vitro; the binding sites are different from the calcium binding sites. The physiological relevance of zinc binding is unclear. Physiological concentrations of potassium antagonize the binding of both divalent cations, especially affecting the high-affinity calcium-binding sites.
