This review lays out the emerging evidence for the fundamental role of Ca2+ stores and store-operated channels in the Ca2+ homeostasis of rods and cones. prevent pathological decrease in [Ca2+]i mediated by excessive activation of PMCA transporters in saturating light. CICR and SOCE may also modulate the transmission of afferent and efferent signals in the… Continue reading This review lays out the emerging evidence for the fundamental role
