Funkcija[uredi | uredi izvor]

Ovaj gen kodira člana porodice alfa-1 podjedinica; a protein u kompleksu naponski ovisnog kalcijskog kanala. Kalcijski kanali posreduju u dotoku iona kalcija u ćeliju nakon polarizaciji membrane i sastoje se od kompleksa podjedinica alfa-1, alfa-2/delta, beta i gama u omjeru 1:1:1:1. Alfa-1 podjedinica ima 24 transmembranska segmenta i formira pore kroz koje ioni prolaze u ćeliju. Postoji više izoformi svakog od proteina u kompleksu, bilo kodiranih različitim genima ili rezultat alternativne prerade transkripata. Alternativne varijante transkripta prerade gena opisanih ovdje su uočene, ali nisu detaljno okarakterisane. Pokazalo se da mutacije u ovom genu uzrokuju nepotpuno X-vezano kongenitalno stacionarno noćno sljepilo tip 2 (CSNB2).^[5]
