English: Photoactivation of PACα mimics forskolin-induced arrest of circus cells in culture. In circus cells in cultures from the X. laevis neural tube, blebs of plasma membrane propagate around the cell circumference with a period of several minutes (Olson, 1996). Forskolin stimulation of endogenous adenylyl cyclases in control cells arrests this blebbing movement (top left panel). Blue light (488 nm) irradiation of mCherry-PACα-expressing cells mimics the effect of forskolin stimulation (top right panel). In contrast, blebbing movements are not affected in non-blue light-irradiated mCherry-PACα-expressing cells (bottom left panel) or in control cells illuminated at 488 nm (bottom right panel). |
