Effect of Cav3.1-GFP and Cav3.2-GFP C-terminal deletions on ankyrin B binding in tsA-201 cells. ( a ) Cav3.1-GFP ∆CT (1851–1875) and wild type channel immunoprecipitates probed with anti-ankyrin B polyclonal antibody. Densitometry analysis of ankyrin B bound to Cav3.1-GFP immunoprecipitates is shown ( P = 0.0005, n = 4). ( b ) Cav3.2-GFP ∆CT (1860–1884) and wild type channel immunoprecipitates probed with anti-ankyrin B polyclonal antibody. Densitometry analysis of ankyrin B bound to Cav3.2-GFP immunoprecipitates is shown ( P = 0.015, n = 4)
