In vertebrates, both α- and β-tubulins have multiple isotypes encoded by different genes, which are intrinsic factors in regulating microtubule functions. However, the structures of microtubules composed of different tubulin isotypes, especially α-tubulin isotypes, remain largely unknown. Here, we purify recombinant tubulin heterodimers composed of different mouse α-tubulin isotypes, including α1A, α1C and α4A, with the β-tubulin isotype β2A. We further assemble and determine the cryo-electron microscopy (cryo-EM) structures of α1A/β2A, α1C/β2A, and α4A/β2A microtubules. Our structural analysis demonstrates that α4A/β2A microtubules exhibit longitudinal contraction between tubulin interdimers compared with α1A/β2A and α1C/β2A microtubules. Collectively, our findings reveal that α-tubulin isotype composition can tune microtubule structures, and also provide evidence for the "tubulin code" hypothesis. | |||||||||

We followed the procedure developed by Dr. Rui Zhang (R. Zhang, Cell, 2015, doi: 10.1016/j.cell.2015.07.012), with all the scripts provided by him. In this way, the generated half-maps have an applied circular mask but without touching the structural outer boundaries. コピー数: 9 / 光学異性体: LEVO EC番号: 加水分解酵素; 酸無水物に作用; GTPに作用・細胞または細胞小器官の運動に関与 |
