Fig. 7. Live cell imaging of HeLa cells co-expressing mRFP-SNX1 and GFP-SNX5 or SNX6. (A,B) SNX1 colocalises with SNX5 (A) or SNX6 (B) on the same vesicles (arrows) and also on tubules emanating from these vesicles (arrowheads) and on pinched-off tubules, suggesting a cooperation between SNX1 and SNX5, and between SNX1 and SNX6 in tubule formation.
