CaV3.1 and CaV3.2 protein levels are reduced in EHD3 cKO atria.
A, CaV3.1 expression was decreased by ∼35% in EHD3 cKO atrial lysates assessed by immunoblot (n = 4 WT, n = 6 EHD3 cKO, p < 0.05). B, CaV3.2 expression was decreased by ∼60% in EHD3 cKO atrial lysates assessed by immunoblot (n = 4 WT, n = 6 EHD3 cKO, p < 0.001). B and C, representative blots of data in A and B. E and F, CaV3.1 and CaV3.2 were undetectable in ventricular lysates.
