motifs/domains
  • N terminus is important for the regulation of voltage-dependent inactivation (VDI)by CABP1
  • four domains of homology
  • a PDZ-binding motif at its cytosolic tail
  • six alpha helical membrane spanning segments (24 transmembrane segments)
  • distal C-terminus (approximately residues 1650-1950) with an important, predominantly inhibitory domain, specific for the heart channel, and containing sites for the SH2 and SH3 binding of Src kinase
  • conjugated GlycoP

  • playing an important role in excitation-contraction coupling in the heart
  • in iron transport into cardiomyocytes under iron-overloaded conditions

  • Ca2+
  • protein
  • CACNA1C targeting to BIN1 is functionally important to cardiac calcium signaling
  • AKAP7 interacts with neuronal CACNA1C via their C terminus
  • serine 1884 is essential for the regulation of CACNA1C by PRKD1
  • interaction between LDB3 and CACNA1C, that facilitated PRKA-mediated phosphorylation of the CACNA1C at Ser1928
  • ADRA1B contraction of vascular smooth muscle involves activation of PLD1, which controls a portion of the ADRA1B-induced CACNA1C channel activity
  • expression of CACNA1C mRNA was rhythmic (peaking during the late night) and regulated by the circadian clock component NR1D1
  • HAP1 is important for insulin secretion of pancreatic beta-cells via regulating the intracellular trafficking and plasma membrane localization of CACNA1C, providing new insight into the mechanisms that regulate insulin release from pancreatic beta cells
