1.A.1.11.6
Voltage-dependent L-type Ca2+ channel subunit α-1C (αCav1.2) of cardiac muscle [A C-terminal fragment of Cav1.2 translocates to the nucleus and regulates transcription, explaining how a channel can directly activate transcription and differentiation of excitable cells.] (Gomez-Ospina et al., 2006). Cav1.2 associates with the α-2, δ-1, β and γ subunits (Yang et al., 2011).
