Nucleation of tubulin
WebThe C. elegans tubulin family is composed of nine α-, six β-, and one γ-tubulin. Tubulins are highly conserved, functioning as α-β heterodimers that assemble into microtubules. These cylindrical and ubiquitous components of the cytoskeleton are critical for nearly all cellular and developmental processes. C. elegans has provided a model for the study of … Web17 nov. 2016 · Patient cells showed decreased levels of polymerized alpha-tubulin (see 602529) and altered microtubule dynamics with decreased nucleation and markedly delayed microtubule repolymerization; microtubules were less abundant and strongly disorganized in both early and late stages of repolymerization, and there was loss of …
