Product Specific Information
Store vial at -20°C prior to opening. Aliquot contents and freeze at -20°C or below for extended storage. Avoid repeated freeze-thaw cycles. Centrifuge product if not completely clear after standing at room temperature.
This product is stable for several weeks at 4°C as an undiluted liquid. Dilute only prior to immediate use.
A BLAST analysis suggests cross-reactivity with rat, human, and mouse based on 100% sequence homology. Cross-reactivity with STIM1 from other sources has not been determined.
Target Information
STIM1 (stromal interacting molecule; also known as GOK) acts as a sensor of calcium depletion within the endoplasmic reticulum and transduces the signal to Orai1, the presumptive CRAC channel at the plasma membrane.
Following a decrease in luminal calcium concentration, STIM1 oligomerizes and induces Orai1 to enable entry of extracellular calcium into the cytoplasm. The precise mechanism of STIM1-Orai1 interaction has not yet been fully elucidated.
STIM1 associates with growing ends of microtubules and is involved in endoplasmic reticulum tubule extension.
