Endocytosis of Wnt ligands from surrounding epithelial cells positions microtubule nucleation sites at dendrite branch points. [PDF]
Microtubule nucleation is important for microtubule organization in dendrites and for neuronal injury responses. The core nucleation protein, γTubulin (γTub), is localized to dendrite branch points in Drosophila sensory neurons by Wnt receptors and ...

Small GTPase ARL4C Associated with Various Cancers Affects Microtubule Nucleation [PDF]
Background/Objectives: The changes in the level of small GTPase ARL4C are associated with the initiation and progression of many different cancers. The content of ARL4C varies greatly between different tissues, and the induction of ARL4C expression leads

Partial closure of the γ-tubulin ring complex by CDK5RAP2 activates microtubule nucleation
Microtubule nucleation is templated by the γ-tubulin ring complex (γ-TuRC), but its structure deviates from the geometry of α-/β-tubulin in the microtubule, explaining the complex's poor nucleating activity.

Detection of Microtubule Nucleation Hotspots at the Golgi. [PDF]
Cell polarization is important for multiple physiological processes. In motile cells, microtubules (MTs) are organized as a polarized array, which is to a large extent comprised of Golgi-derived MTs (GDMTs), which asymmetrically extend toward the cell front.

Direct induction of microtubule branching by microtubule nucleation factor SSNA1 [PDF]
Microtubules are central elements of the eukaryotic cytoskeleton that often function as part of branched networks. Current models for branching include nucleation of new microtubules from severed microtubule seeds or from γ-tubulin recruited to the side ...

Reconstitution of Microtubule Nucleation In Vitro Reveals Novel Roles for Mzt1. [PDF]
Summary Microtubule (MT) nucleation depends on the γ-tubulin complex (γ-TuC), in which multiple copies of the heterotetrameric γ-tubulin small complex (γ-TuSC) associate to form a ring-like structure (in metazoans, γ-tubulin ring complex; γ-TuRC) [1, 2 ...

Insight into microtubule nucleation from tubulin-capping proteins
Significance Microtubules are involved in many key functions of eukaryotic cells, including cell division, intracellular transport, and cell shape. They are hollow tubes made of parallel filaments, themselves formed by the self-assembly of αβ-tubulin ...

The XMAP215 Ortholog Alp14 Promotes Microtubule Nucleation in Fission Yeast
SUMMARY The organization and number of microtubules (MTs) in a cell depends on the proper regulation of MT nucleation. Currently, the mechanism of nucleation is the most poorly understood aspect of MT dynamics.

Microtubule nucleation and organization without centrosomes.
Centrosomes play various critical roles in animal cells such as microtubule nucleation and stabilization, mitotic spindle morphogenesis, and spindle orientation. Land plants have lost centrosomes and yet must execute many of these functions.

Stu2/XMAP215/ZYG-9/Dis1/Alp14/Msps/ch-TOG family members in association with with γ-tubulin complexes nucleate microtubules, but we know little about the interplay of these nucleation factors. Here, we show that the budding yeast Stu2 in complex with the
