Description:
The links between the cell cycle machinery and the cytoskeletal proteins controlling cytokinesis are poorly understood. The small guanine nucleotide triphosphate (GTP)-binding protein RhoA stimulates type II myosin contractility and formin-dependent assembly of the cytokinetic actin contractile ring. We found that budding yeast Polo-like kinase Cdc5 controls the targeting and activation of Rho1 (RhoA) at the division site via Rho1 guanine nucleotide exchange factors. This role of Cdc5 (Polo-like kinase) in regulating Rho1 is likely to be relevant to cytokinesis and asymmetric cell division in other organisms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yoshida, Satoshi -- Kono, Keiko -- Lowery, Drew M -- Bartolini, Sara -- Yaffe, Michael B -- Ohya, Yoshikazu -- Pellman, David -- New York, N.Y. -- Science. 2006 Jul 7;313(5783):108-11.
