Biochem/physiol Actions

The calcium channel, voltage-dependent, N type, α1B subunit (CACNA1B) or Cav2.2 is encoded by the CACNA1B gene in humans and belongs to the family of voltage-gated calcium channels. It serves as the key transducers of cell surface membrane potential changes into local intracellular calcium transients that initiate many different physiological events. CACNA1B is expressed primarily in the neurons, have various roles in neuronal functions and are especially involved with neurotransmitter release at the sympathetic nerve terminals. It is localize to presynaptic nerve terminals of nociceptors where they control neurotransmitter release. Ca(v)β subunit relative to the α(1)2.2 subunit is critical, and the points of contact between these subunits are required for Ca(v)β to regulate channel activity. CACNA1B regulate the trafficking and biophysical properties of various channels.
