The expression of chimeras that consist of a fluorescent protein (FP) conjugated with a protein of interest provides the ability to visualize, track, and quantify the subcellular localization and dynamics of specific proteins in biological samples. Array confocal laser scanning microscopy is an eminently suitable technique for live-cell imaging of FP-tagged fusion proteins. Here, we describe real-time monitoring of the subcellular dynamics of the stromal-interacting molecule 1 (STIM1) and Orai1, the key protagonists of store-operated Ca2+ entry (SOCE) under resting conditions, and upon Ca2+ mobilization from the endoplasmic reticulum (ER).
