WebJun 14, 2024 · Neurons depend on the highly dynamic microtubule (MT) cytoskeleton for many different processes during early embryonic development including cell division and migration, intracellular trafficking and signal transduction, as well as proper axon guidance and synapse formation. The coordination and support from MTs is crucial for newly … WebFeb 14, 2013 · Branching microtubule nucleation requires γ-tubulin and augmin and is stimulated by factors previously implicated in chromatin-stimulated nucleation, guanosine …
Branching Microtubule Nucleation in Xenopus Egg Extracts …
WebMore specifically, TPX2 contributes to microtubule branching during spindle assembly by cooperating with augmin in order to amplify microtubule mass and preserve its polarity. Branching nucleation by TPX2 is observed without RanGTP, though more fan-shaped microtubule structures are formed when both RanGTP and TPX2 are present. WebApr 13, 2024 · Branching microtubule nucleation relies on the hetero-octameric augmin complex, but lack of structure information about augmin has hindered understanding how it promotes branching. In this work ... theatre asylum
Biochemical reconstitution of branching microtubule …
WebTPX2 and augmin enable γ-TuRC-dependent microtubule nucleation at preferred branching angles of less than 90 degrees from regularly-spaced patches along … WebIn cell biology, microtubule nucleation is the event that initiates de novo formation of microtubules (MTs). ... Branching MT nucleation. Studies using Xenopus egg extracts have identified a novel form of microtubule nucleation that generates fan-like branching arrays, in which new microtubules grow at an angle off of older microtubules. ... WebJan 21, 2024 · The branching microtubule nucleation is crucial because it allows the cells to form a huge amount of microtubules enabling the capture of the chromosomes.
