R형 칼슘 채널은 전압 의존형 칼슘 채널의 한 종류입니다.이 등급의 다른 단위와 마찬가지로, α 서브유닛은1 칼슘이 세포로 들어가는 모공을 형성하고 대부분의 채널 특성을 결정합니다.이1 α 서브유닛은 CACNA1E[1][2][3]유전자에 의해 인간에서 코드되는 칼슘 채널, 전압 의존형, R형, 알파 1E 서브유닛(CACNA1E)또는2.3 Cav로도 알려져 있다.그것들은 피질, 해마, 선조체, 편도체 및 분자간 [4]핵에서 강하게 발현된다.
그것들은 잘 이해되지 않지만, Q형 칼슘 채널과 마찬가지로 소뇌 과립 세포에 존재하는 것으로 보인다.그들은 활성화의 문턱이 높고 상대적으로 느린 운동성을 가지고 있다.
