Septin ring

From Wikipedia, the free encyclopedia

A septin ring forms during cell division. The collar-shaped structure forms along the axis where the cell splits and is composed of septins and associated proteins [1].The formation has been seen in the budding of fungal cells such as yeast, the cytokinesis of animal cells, within the hyphae of filamentous fungi, and at pseudohyphal projections [2]. In yeast cells, the septin ring serves as a "dock" and proteins bind to it in an asymmetrical fashion. The functions of the septin structure are not fully understood and research is ongoing [1].
