STIM1 is a Ca sensing protein residing in the endoplasmic reticulum(ER).Once the ER Ca stores are depleted,STIM1 moves towards the plasma membrane(PM)(translocation),forms puncta(clustering),and triggers store-operated Ca entry(SOCE).Although this process has been regarded as a main mechanism for store-operated Ca channel activation,the mechanism of STIM1 clustering is still *** we discovered a new phenomenon of STIM1 clustering,which is not
