Rat Protein S100-A1, S100A1 ELISA Kit, 96T

Probably acts as a Ca(2+) signal transducer (By similarity). In response to an increase in intracellular Ca(2+) levels, binds calcium which triggers a conformational change (PubMed: 16169012, PubMed: 18650434). This conformational change allows interaction of S1001A with specific target proteins, such as TPR-containing proteins, and the modulation of their activity (By similarity).
