The contractile ring
نویسنده
چکیده
What is the contractile ring? During cell division, the contractile ring generates the constricting force to separate one cell into two cells. Formed during cytokinesis, the last step of cell division, the contractile ring is composed of filamentous actin (F-actin) and the motor protein myosin-2, along with additional structural and regulatory proteins. The contractile ring forms under the surface of the plasma membrane and is linked to the plasma membrane such that, when it constricts, it creates a cleavage furrow that partitions the cell in two.

Aim44p regulates phosphorylation of Hof1p to promote contractile ring closure during cytokinesis in budding yeast
Whereas actomyosin and septin ring organization and function in cytokinesis are thoroughly described, little is known regarding the mechanisms by which the actomyosin ring interacts with septins and associated proteins to coordinate cell division. Here we show that the protein product of YPL158C, Aim44p, undergoes septin-dependent recruitment to the site of cell division. Aim44p colocalizes wit...
متن کاملContraction and polymerization cooperate to assemble and close actomyosin rings around Xenopus oocyte wounds
Xenopus oocytes assemble an array of F-actin and myosin 2 around plasma membrane wounds. We analyzed this process in living oocytes using confocal time-lapse (four-dimensional) microscopy. Closure of wounds requires assembly and contraction of a classic "contractile ring" composed of F-actin and myosin 2. However, this ring works in concert with a 5-10-microm wide "zone" of localized actin and ...

During cytokinesis, the actomyosin contractile ring drives ingression of the overlying plasma membrane. A recent study has provided mechanistic insight into how the contractile ring might contribute to membrane ingression.

Angiotensin-converting enzyme (ACE) inhibitors including quinapril could exert a protective effect on cardiovascular system through endothelial system in normoglycemic and diabetic rats. The present experimental work was designed to study the vascular reactivity of aortic ring segments isolated from streptozotocin (STZ)-diabetic rats treated for 4 weeks with nitro-L-arginine-methyl ester (L-NAM...
متن کاملRedistribution of Actin during Assembly and Reassembly of the Contractile Ring in Grasshopper Spermatocytes
Cytokinesis in animal cells requires the assembly of an actomyosin contractile ring to cleave the cell. The ring is highly dynamic; it assembles and disassembles during each cell cleavage, resulting in the recurrent redistribution of actin. To investigate this process in grasshopper spermatocytes, we mechanically manipulated the spindle to induce actin redistribution into ectopic contractile ri...
