AtABCG14 forms homodimers in vivo.
(A) Reciprocal co-immunoprecipitation (coIP) assay of Myc-AtABCG14 and FLAG-AtABCG14 in human HEK293T cells. Total protein was extracted from human HEK293T cells transfected with Myc-AtABCG14 and FLAG-AtABCG14.
(B and C) CoIP assay of GFP-AtABCG14 and Myc-AtABCG14 expression in tobacco leaves (B) and Arabidopsis(C). Total protein was extracted from tobacco leaves (B) and 25-DAG transgenic plants (C) co-expressing GFP-AtABCG14 and Myc-AtABCG14.
