Aug 18, 2021 · Microtubule dynamics and their control are essential for the normal function and division of all eukaryotic cells. This plethora of functions is, in large part, supported by dynamic microtubule ...
Apr 19, 2018 · The conformational cycle of tubulin is directly linked to microtubule dynamics. Microtubule dynamics also depend on the size and composition of the stabilizing cap, loss of which leads to ...

Aug 14, 2020 · Tubulin PTMs can modulate MT dynamics directly or indirectly by influencing the interactions between MTs and microtubule-interacting proteins (which can stabilize, destabilize, or cut microtubules). While for the vast majority of modifying enzymes, a tubulin heterodimer already incorporated into the microtubule lattice is a preferred substrate, in some cases, free tubulin heterodimers are ...

Sep 9, 2020 · Interestingly, similar to doublecortin, EB proteins bind at the corner of four tubulin heterodimers, but they interfere with microtubule dynamics in a different manner. Although a mild increase of microtubule growth has been measured in in vitro experiments, the most obvious effect of EBs is to enhance catastrophe frequency, making microtubules more dynamic ( Duellberg et al., 2013 ).

In animal cells, the major microtubule-organizing center is the centrosome, which is located adjacent to the nucleus near the center of interphase (nondividing) cells (Figure 11.39). During mitosis, microtubules similarly extend outward from duplicated centrosomes to form the mitotic spindle, which is responsible for the separation and distribution of chromosomes to daughter cells.

May 24, 2021 · In addition to exerting their influence at microtubule ends, regulatory proteins can also affect microtubule structure and dynamics through interactions with the microtubule lattice. Tubulin subunits can be removed from the lattice by physical perturbations, such as bending 46–48 , or by chemomechanical forces exerted by microtubule-severing proteins such as spastin and katanin 99–102 .
