Examples of Abscission


13 examples:

Say abscission with precision, Now: position and transition.

Abscission is executed by a protein machinery named ESCRT-III.
(Science Daily - News, )

Scientists explain a flower's petal-shedding process called abscission.
(Tech Times - Science, )

At the very end, “cellular abscission” splits the membrane and thereby gives birth to two daughter cells.
(Science Daily - News, )

A study sheds new light on the process that governs how and when plants shed their petals, a process known as abscission.
(Science Daily - News, )

In the presence of incorrectly segregated chromosomes, the Aurora-B-dependent abscission checkpoint prevents the final stage of cytokinesis.
(Nature Cell Biology, )

The endosomal sorting complex required for transport (ESCRT)-III is critical for membrane abscission; however, the mechanism underlying ESCRT-III-mediated membrane constriction remains elusive.
(Nature Cell Biology, )

A study of the dynamic assembly and disassembly of the ESCRT-III machinery in vitro and in vivo now suggests that the turnover of the observed spiralling filaments is critical for membrane abscission during cytokinesis.
(Nature Cell Biology, )

How annular fusion is accomplished is unknown, but it is thought to involve the p97 AAA-ATPase complex and bears a topological equivalence to the membrane fusion event that occurs during the abscission phase of cytokinesis.
(Nature, )

Here, Petsalaki and Zachos report that Cdc-like kinases (Clks) 2 and 4 localize to the midbody and phosphorylate the mitotic kinase Aurora B, imposing the abscission checkpoint to prevent premature abscission and chromatin breakage.
(Nature Communications, )

Mendoza and colleagues provide insights into the specificity of the NoCut checkpoint, showing that although different types of chromosomal defects delay cytokinetic abscission, only after replication stress does this prevent DNA damage.
(Nature Cell Biology, )

Cell division at the abscission zone of the short-lived cultivar occurred earlier than in the long-lived cultivar, indicating that the tempo of development differed; the abscission layer reached full maturity sooner in Procut Bicolor, resulting in earlier petal drop, than in Procut Yellow Lite.
(Science Daily - News, )

We propose that ESCRT-III, VPS4 and spastin cooperate to coordinate nuclear envelope sealing and spindle disassembly at nuclear envelope–microtubule intersection sites during mitotic exit to ensure nuclear integrity and genome safeguarding, with a striking mechanistic parallel to cytokinetic abscission.
(Nature, )
