Midbody ringMidbody ringThe midbody ring is a circular structure located at the core of the midbody in the cytokinetic bridge. It is a highly dense structure that contains microtubules as well as remnants from the contractile ring. The midbody ring acts as a scaffold for factors involved in the final stages of cytokinesis. Immunofluorescent stainingThe midbody is a transient structure present during the final stages of cytokinesis. The midbody ring can be seen as a circular structure in the bulging region at the center of the midbody that lacks staining of the microtubule marker. Read more about the proteome of the midbody ring as a substructure of microtubules. CTTNBP2Cortactin-binding protein 2 (CTTNBP2), is a regulator of actin filaments that is important for dendritic spine formation and maintenance. It also binds to microtubules and induces microtubule bundle formation. |
