Voltage-dependent Ca2+ channels provide a pathway for rapid influx of Ca2+ into cells, which plays a crucial role in both electrical and metabolic signaling.1
T-type currents are transduced via channel proteins encoded by three genes that compose a subfamily within the CaV channel family.2-3
The activity of T-type channels contributes to several known physiological and pathophysiological phenomena including burst firing in neurons, pacemaking activity in the heart and secretion from endocrine tissues.2 There are three cloned T-type channel isoforms.
CACNA1G (CaV3.1) and CACNA1H (CaV3.2) are widely distributed whereas the expression of CACNA1I (CaV3.3) is restricted to the central nervous system.2
CACNA1G and CACNA1H are also expressed in the kidney, but little is known about their physiological role there.

Anti-CACNA1G (CaV3.1) Antibody (#ACC-021) is a highly specific antibody directed against an epitope of the rat CaV3.1 channel. The antibody can be used in western blot, immunocytochemistry, and immunohistochemistry applications. It has been designed to recognize CACNA1G from human, rat, and mouse samples.

Immunohistochemical staining of mouse kidney sections using Anti-CACNA1G (CaV3.1) Antibody (#ACC-021). A. CaV3.1 (purple) is detected in the pelvis kidney junction (PKJ). B. HCN3 staining (green), a marker of pacemaker cells, is detected in the PKJ. C. Same section stained for CaV3.1 (red). D. Merge of B and C panels shows high degree of co-localization between CaV3.1 and HCN3.
