Exogenous expression of Golgin45.D171A mutant results in intercisternal fusion. (A) Both WT Golgin45 and Golgin45.D171A mutant significantly co-localized with endogenous Syntaxin5 in HeLa cells. GT-GFP was co-expressed as a Golgi marker. Bar = 10 μm (B) Representative EM photo showing that expression of Golgin45.D171A mutant, but not the Golgin45 WT, results in frequent intercisternal fusions at the Golgi in HeLa cells. Insets show a magnified view of the boxed area. Intercisternal fusions are marked by black arrow heads. (scale bar = 1 μm) M = mitochondria, N = nucleus, G = Golgi.
