Protein Information (annotations from UniProt)

Database IDHIV0002577
UniProt IDP06703
Primary gene name(s)S100A6
Synonym gene name(s)CACY
Protein nameProtein S100-A6
Protein functionMay function as calcium sensor and modulator, contributing to cellular calcium signaling. May function by interacting with other proteins, such as TPR-containing proteins, and indirectly play a role in many physiological processes such as the reorganization of the actin cytoskeleton and in cell motility. Binds 2 calcium ions. Calcium binding is cooperative. {ECO:0000269|PubMed:22399290}.
Subcellular locationNucleus envelope. Cytoplasm. Cell membrane;
