Physiological studies have established the role of plant high-capacity vacuolar H+/Ca2+ exchange activity in ion homeostasis and signal transduction. The molecular characterization and structure-function analyses of these transporters are just beginning to emerge. In yeast, Ca2+ signaling molecules regulate vacuolar H+/Ca2+ exchange. Recently, some of the Ca2+ dependent "molecular relay" molecules have been characterized in plants; however, the regulation of plant vacuolar H+/Ca2+ exchange remains an open question.
生理学研究已证实植物高容量液泡H⁺/Ca²⁺交换活性在离子稳态和信号转导中的作用。这些转运蛋白的分子特征及结构-功能分析才刚刚起步。在酵母中，Ca²⁺信号分子调节液泡H⁺/Ca²⁺交换。最近，一些Ca²⁺依赖性“分子中继”分子已在植物中得到表征；然而，植物液泡H⁺/Ca²⁺交换的调节仍是一个悬而未决的问题。
