Web30 apr. 2024 · The actomyosin contractile ring is anchored to the midbody by septin–anillin complexes, which also aid the recruitment of abscission machinery to the midbody . In doing so, and in direct interactions with microtubule-binding proteins such as MAP4 ( 32 ), septins facilitate microtubule depolymerization and the completion of cytokinesis. Web1 okt. 2024 · Abscission is the second stage of cytokinesis. Cep55, a coiled-coil protein, is thought to recruit endosomal sorting complexes required for transport (ESCRTs) to the midbody to complete abscission. However, recent studies of Cep55-knockout mice reveal that most cells can complete abscission without Cep55.
