Open the CACNA1H IHC GuideFacts about Voltage-dependent T-type calcium channel subunit alpha-1H.
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 function pacemaking functions in both central neurons and cardiac nodal cells and support calcium signaling in secretory cells and vascular smooth muscle (Probable).

In nonneuronal tissues, the highest expression levels are found in the kidney, liver, and heart. 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).
Cell membrane; Multi-pass membrane protein. Interaction with STAC increases expression at the cell membrane.
