Ca2+ is the most widely used second messenger in cell biology and fulfills a plethora of essential cell functions. One of the most exciting findings of the last decades was the involvement of Ca2+ in the regulation of long-term cell adaptation through its ability to control gene expression. This finding provided a link between cell excitation and gene expression. In this review, we chose to focus on the role of voltage-dependent calcium channels in mediating gene expression in response to membrane depolarization. We illustrate the different pathways by which these channels are involved in excitation-transcription coupling, including the most recent Ca2+ ion-independent strategies that highlight the transcription factor role of calcium channels.
钙离子(Ca2+)是细胞生物学中使用最广泛的第二信使,履行着大量重要的细胞功能。过去几十年中最令人兴奋的发现之一是,Ca2+通过其控制基因表达的能力参与长期细胞适应性调节。这一发现建立了细胞兴奋与基因表达之间的联系。在本综述中,我们选择重点关注电压依赖性钙通道在介导膜去极化响应中的基因表达方面的作用。我们阐述了这些通道参与兴奋-转录偶联的不同途径,包括突出钙通道转录因子作用的最新非钙离子依赖策略。
