Septins是什么
WebSeptins belong to the superclass of phosphate-binding loop (P-loop) NTPases which includes the oncogenic RAS GTPases. Structurally, the septins have an amino terminal region with Proline -rich domains, a … 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, …
