Voltage-sensitive calcium channel that gives rise to T-type calcium currents. T-type calcium channels belong to the "low-voltage activated (LVA)" group. A particularity of this type of channel is an opening at quite negative potentials, and a voltage-dependent inactivation (PubMed:9670923, PubMed:9930755, PubMed:27149520). T-type channels serve pacemaking functions in both central neurons and cardiac nodal cells and support calcium signaling in secretory cells and vascular smooth muscle (Probable). They may also be involved in the modulation of firing patterns of neurons (PubMed:15048902). In the adrenal zona glomerulosa, participates in the signaling pathway leading to aldosterone production in response to either AGT/angiotensin II, or hyperkalemia (PubMed:25907736, PubMed:27729216).Curated5 Publications

Channel activity is strongly inhibited by mibefradil (PubMed:9670923, PubMed:9930755). Channel activity is strongly inhibited by Ni2+ ions (PubMed:9930755).2 Publications

In the brain, most abundant in the amygdala, caudate nucleus, and putamen (PubMed:9670923, PubMed:9930755). In the heart, expressed in blood vessels. Isoform 1 and isoform 2 are expressed in testis, primarily in the germ cells, but not in other portions of the reproductive tract, such as ductus deferens. Isoform 2 is not detected in brain (PubMed:11751928). Expressed in the adrenal glomerulosa (at protein level) (PubMed:25907736, PubMed:27729216).5 Publications
