WebSeptins are GTP-binding proteins that are evolutionarily and structurally related to the RAS oncogenes. Septin expression levels are altered in many cancers and new advances point to how abnormal septin expression may contribute to the progression of cancer. In contrast to the RAS GTPases, which are frequently mutated and actively promote tumorigenesis, … WebApr 23, 2024 · Septins do not have any specific organization early in the cell cycle but arrange at the mother bud-neck of yeast into higher-order ring structures as the bud emerges. The septin rings remain at the site of division after cytokinesis and can thus be observed in the mother and daughter cells (2). Septins evidently play a role in the … WebDec 6, 2024 · Septins function in a physiological manner to align with scaffolds (tubulin, actin, and vimentin) to allow for compartmentalization. In yeast, Septins control the diffusion of specific proteins between mother and bud cells, regulating cellular aging (Takizawa et al, 2000; Shcheprova et al, 2008).
