Extended Data Fig. 10: Mitochondria- and ER-associated actin accumulates during ER-mediated mitochondrial fission.
From: Actin chromobody imaging reveals sub-organellar actin dynamics

a) AC-ER specifically accumulates at fission sites prior to ER-mediated fission. AC-ER accumulation is evident during ER-mediated mitochondrial fission. Hollow arrows mark the location of mitochondrial fission. Yellow lines in the left column mark the area used to generate the line scans. Scale bar: 1 µm. Example images of the areas used to determine the degree of MitoTracker overlap and coefficient of variance for mCherry/AC-ER and the resulting values are also shown. These results were reproducible across 19 independent experiments. b) AC-mito accumulates prior to ER-mediated fission. Same as A with cells expressing AC-mito instead of AC-ER.
