Kinetochore

…Other proteins that are involved in the polymerization of microtubules and interactions between microtubules and other filamentous structures include tau proteins and microtubule-associated proteins (MAPs), which are small proteins that are necessary for the polymerization of microtubules and interactions between other filamentous structures. During eukaryotic cell division, microtubules form spindle fibers that emanate from centrioles located at both poles of the spindle and bind to the kinetochores of chromosomes, and play a role in chromosome separation. During interphase, microtubules emanate from the microtubule-organizing centre (MOC), which is located in the cytoplasm close to the nucleus, and run radially towards the cell periphery. …

…そのほかに，微小管の重合や他の繊維構造との間の相互作用に必要なτタンパク質や微小管結合タンパク質(MAP)など少量のタンパク質がこの構造に加わっている。真核細胞の分裂には，微小管が紡錘体の両極に位置する中心粒から発する紡錘糸として，染色体の動原体kinetochoreに結合し，染色体分離の役割を果たす。分裂間期に入ると，微小管は核に近い細胞質に位置している微小管形成中心(microtubule‐organizing centre＝MOC)から発して，放射状に細胞周縁に向かって走る。…
