Rhodblock 3 acts upstream of Rok in Drosophila, resulting in the downregulation of Rok and inhibition of myosin phosphorylation. Rhodblock 3 inhibits phospho-MRLC localization as well as furrow localization of the septin Peanut and increased Peanut’s localization on microtubules but did not affect other proteins tested, such as Anillin.
