Microtubule growth with maps
Web5 sep. 2024 · Microtubules are highly dynamic filaments assembled from αβ-tubulin heterodimers and play important roles in many cellular processes, including cell division and migration. Microtubule dynamics is tightly regulated by microtubule-associated proteins (MAPs) that function by binding to microtubules or free tubulin dimers. WebIt is well established that a plethora of tubulin and microtubule associated proteins (MAPs) are able to shape the biomechanical properties of microtubules, thus introducing a …

WebRecent studies have found that microtubule-associated proteins (MAPs) can regulate the dynamical properties of microtubules in unexpected ways. For most MAPs, there is an inverse relationship between their effects on the speed of growth and the frequency of catastrophe, the conversion of a growing microtubule to a shrinking one.

Three subgroups of microtubules aid in the process of mitosis: astral, polar, and kinetochore microtubules. Astral microtubules radiate from the MTOCs of a cell to the cell membrane, keeping the mitotic spindle in place.
