γ-TuRC asymmetry induces local protofilament mismatch at the RanGTP-stimulated microtubule minus end
The γ-tubulin ring complex (γ-TuRC) is a structural template for de novo microtubule assembly from α/β-tubulin units. The isolated vertebrate γ-TuRC assumes an asymmetric, open structure deviating from microtubule geometry, suggesting that γ-TuRC closure

Myomegalin is necessary for the formation of centrosomal and Golgi-derived microtubules
Summary The generation of cellular microtubules is initiated at specific sites such as the centrosome and the Golgi apparatus that contain nucleation complexes rich in γ-tubulin.

Nucleation and the kinetics of microtubule assembly. [PDF]
A kinetic model was developed for the purpose of interpreting scanning calorimetric data of microtubule assembly. The model consists of two steps. The first step is a highly exothermic nucleation with a strong dependence upon temperature and concentration.

Abstract figure legend Schematic outlining the activation of hypoxia‐sensitive pathways, the influence of hypoxia and associated pathways on the cytoskeleton, and the impact of these on disease progression. Abstract A highly‐regulated and dynamic cytoskeleton is vital for functional cellular physiology and the maintenance of homeostasis.

Molecular insight into microtubule nucleation by the XMAP215/γ-TuRC module
It has become increasingly evident in recent years that nucleation of microtubules from a diverse set of microtubule organizing centers (MTOCs) requires both the γ-tubulin ring complex (γ-TuRC) and the microtubule polymerase XMAP215.

Microtubules are organized independently of the centrosome in
Background The best-studied arrangement of microtubules is that organized by the centrosome, a cloud of microtubule nucleating and anchoring proteins is clustered around centrioles.

How microtubules (MTs) are generated in the cell is a major question in understanding how the cytoskeleton is assembled. For several decades, γ-tubulin has been accepted as the universal MT nucleator of the cell. Although there is evidence that γ-tubulin

Unveiling the Functional Role of KIF21B in Microglia Inflammatory Response
Microglia express KIF21B in both sexes. KIF21B binds to microglia cytoskeleton; inflammation alters such interaction promoting a phagocytic state in females. In male microglia KIF21B modulates migration. ABSTRACT Microglia are brain immune cells that maintain homeostasis and respond to injury, changing cell morphology to drive inflammation, migration ...

Determining how microtubules (MTs) are nucleated is essential for understanding how the cytoskeleton assembles. While the MT nucleator, γ-tubulin ring complex (γ-TuRC) has been identified, precisely how γ-TuRC nucleates a MT remains poorly understood ...

Deep Mutational Scanning for the Study and Engineering of Protein Assemblies
This review explores how deep mutational scanning (DMS) can be used to improve understanding and accelerate engineering of protein assemblies, from natural fibers to engineered nanocages. We discuss various types of protein assemblies and their characterization, provide an introduction to the DMS technique, and then highlight examples in which DMS has ...
