Stromal interaction molecule 1 (STIM1) is a transmembrane protein of the endoplasmic reticulum (ER) , a Ca2+ transducer in ER that activates the store-operated calcium channel.Through Orai1 protein, STIM1 adjusts the intracellular and extracellular calcium concentration.This way is called a store-operated Ca2+ entry.STIM1 plays a key role in phenotypic transformation of vascular smooth muscle cells, proliferation of endothelial cells, myocardial hypertrophy and myocardial fibrosis to regulate lots of cardiovascular diseases, such as atherosclerosis, congestive heart failure and systemic hypertension.STIM1 is closely related to cardiovascular diseases through calcium signal.The research progress of STIM1 in cardiovascular diseases is mainly discussed in this article.
