Introduction
Microtubules are long, hollow cylinders made up of polymerised - and -tubulin dimers. Tubulin dimers polymerize end to end in protofilaments which are the building block for the microtubule structure. Microtubules are part of a structural network (the cytoskeleton) within the cells cytoplasm. The primary role of the microtubule cytoskeleton is mechanical. However, in addition to structural support, microtubules also take part in many other processes. A microtubule is capable of growing and shrinking in order to generate force, and there are also motor proteins that allow organelles and other cellular factors to be carried along a microtubule.
Tubulin is a highly-conserved major component of eukaryotic cells and the ‘building block’ of microtubules. Tubulin is a heterodimer of and subunits with an apparent molecular mass of ~110 kDa. In vivo and in vitro, in the presence of GTP, tubulin heterodimers can polymerize (assemble) to form microtubules.
Many proteins or small-molecule compounds affect microtubule assembly. EMD Millipore’s In vitro Tubulin Polymerization Assay Kit allows for quick and quantitative determination of tubulin polymerization due to protein and compound-based modulation.
