Calcium channel-related gene expression

The term "calcium channel-related gene expression" refers to the changes in gene transcription that are regulated by the activity of calcium channels, especially *voltage-gated calcium channels (VGCCs)* and other related channels such as NMDA receptors. Calcium influx through these channels activates various intracellular signaling cascades—including the calmodulin-CaM kinase and CREB phosphorylation pathways—that ultimately alter transcription of responsive genes like *c-fos* and *BDNF*. Additionally, auxiliary subunits such as CaVβ may enter the nucleus and directly or indirectly modulate gene expression. This process plays a crucial role in neuronal excitability, synaptic plasticity, muscle development, cell proliferation, and apoptosis. Abnormal gene expression linked to calcium channel signaling has been implicated in diseases including epilepsy, neurodegeneration, and cardiovascular disorders. However, there is no single protein or receptor called "calcium channel-related gene expression"; the phrase describes a cellular mechanism, making it unsuitable as a target entry for structured databases.
