Dihydropyridine-sensitive L-type, Ca2+ channel subunit, Cav2.2, α2δ subunit 1, CACNA2D1, NL2A, CCHL2A, MHS3.  An N-terminal region (the R-domain) is necessary and sufficient for Cav2.2 regulation (Song et al. 2015). This subunit is regulated at the transcriptional level by microRNA, MiR-183, which thereby regulates nociceptive basal and neuropathic pain (Peng et al. 2017).

CACHD1 of 1274 aas and 2 TMSs.  CACHD1 is structurally an α2δ-like protein that functionally increases CaV3 calcium current. CACHD1 increases the presence of CaV3.1 (TC# 1.A.1.11.12) at the cell surface, forms complexes with CaV3.1, and causes an increase in channel open probability. In hippocampal neurons, CACHD1 causes increases in neuronal firing. Thus, CACHD1 modulates CaV3 activity (Cottrell et al. 2018).
