Highlights
The role of voltage-dependent calcium (Cav1) channels is prominent in excitable cells while store-operated calcium channels (SOCC) were considered as characteristic of non-excitable cells
The calcium concentration in the external medium is about 1–2 mM, whereas the [Ca]i is about 50–100 nM and depends on the calcium channels expressed at both the cell and endoplasmic reticulum (ER) membranes, on exchangers, pumps
IP3 binds to its receptors on the ER membrane leading to the release of ER Ca2+ stores, which induces a conformational change of STIM1, an ER Ca2+ sensor
Summary
The role of voltage-dependent calcium (Cav1) channels is prominent in excitable cells while store-operated calcium channels (SOCC) were considered as characteristic of non-excitable cells. The absence of cell membrane depolarization upon activation and possible non-specific effects of the drugs questioned the putative role of Cav1 channels in T-cells.
