A single microtubule contains 10 to 15 protofilaments (13 in mammalian cells) that wind together to form a 24 nm wide hollow cylinder. Microtubules are structures that can rapidly grow (via ...
Microtubules tend to grow out from the centrosome to the plasma membrane. In nondividing cells, microtubule networks radiate out from the centrosome to provide the basic organization of the ...
Their findings, published in Developmental Cell, shed light on how a protein called CDK5RAP2 activates the microtubule nucleator γ-tubulin ring complex (γTuRC), a key component of this skeleton ...
