Voltage-dependent calcium channels are important for the release of neurotransmitters into neurons. L-type (long lasting current) voltage-dependent calcium channels are composed of four subunits: an å1 subunit, a ∫ subunit, a © subunit and an å2/∂ subunit. The © subunit is made of eight distinct proteins (designated L-type Ca++ CP ©1-©8) and functions by influencing the properties of the calcium current. L-type Ca++ CP ©3, also known as CACNG3 or Cacng2, is a 315 amino acid multi-pass membrane protein that belongs to the CACNG family. As one of the eight gamma subunits, L-type Ca++ CP ©3 is thought to stabilize the calcium current when the calcium channel is in a closed (inactivated) state. Defects in the gene encoding L-type Ca++ CP ©3 may be associated with familial infantile convulsive disorder with paroxysomal choreoathetosis, an autosomal dominant neurological disorder. |
