Stromal interaction molecule 1 plays a role in mediating Ca(2+) influx following depletion of intracellular Ca(2+) stores.
It acts as Ca(2+) sensor in the endoplasmic reticulum via its EF-hand domain.
Upon Ca(2+) depletion, it translocates from the endoplasmic reticulum to the plasma membrane where it activates the Ca(2+) release-activated Ca(2+) (CRAC) channel subunit.
A band is seen at ~77kD, representing the STIM-1 protein.
Two other non-specific bands of lower MW can also be seen
Optimal dilutions to be determined by the researcher.
Cellular Localization: Cell membrane, ER membrane.
Translocates from ER to cell membrane in response to depletion of intracellular calcium.
Positive Controls: HeLa whole cell lysate
Storage and Stability:May be stored at 4°C for short-term only.
For long-term storage and to avoid repeated freezing and thawing, aliquot and store at -20°C.
Aliquots are stable for at least 12 months at -20°C.
For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
Further dilutions can be made in assay buffer.
