Entrez gene summary

Voltage-sensitive calcium channels mediate the entry of calcium ions into excitable cells, and are also involved in a variety of calcium-dependent processes, including muscle contraction, hormone or neurotransmitter release, gene expression, cell motility, cell division, and cell death. This gene encodes a T-type, low-voltage activated calcium channel. The T-type channels generate currents that are both transient, owing to fast inactivation, and tiny, owing to small conductance. T-type channels are thought to be involved in pacemaker activity, low-threshold calcium spikes, neuronal oscillations and resonance, and rebound burst firing. Many alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Sep 2011]

Staining summary

Strong cytoplasmic immunoreactivity was observed in muscle cells, adipose tissue and in stroma. Cilia of fallopian tube and respiratory epithelia were strongly positive. Most other normal tissues showed weak to moderate cytoplasmic staining. Lymphoid tissues were negative.
