Paclitaxel binds to tubulin, strongly promotes microtubule assembly from subunits, and stabilizes the assembled polymer against disassembly. Because of its ability to drive the assembly reaction almost completely toward microtubules, the paclitaxel-dependent procedure outlined here is particularly useful for the isolation of microtubules from tissues in which the intracellular concentration of tubulin is low (e.g., nonneuronal sources, cultured cells, and invertebrate tissues). The microtubule-associated proteins (MAPs) remain bound to the paclitaxel-stabilized microtubules. The isolation of these MAPs by salt extraction is also described here.

UI	MeSH Term	Description	Entries
D008869	Microtubule-Associated Proteins	High molecular weight proteins found in the MICROTUBULES of the cytoskeletal system. Under certain conditions they are required for TUBULIN assembly into the microtubules and stabilize the assembled microtubules.

D008870	Microtubules	Slender, cylindrical filaments found in the cytoskeleton of plant and animal cells. They are composed of the protein TUBULIN and are influenced by TUBULIN MODULATORS.	Microtubule
D011485	Protein Binding	The process in which substances, either endogenous or exogenous, bind to proteins, peptides, enzymes, protein precursors, or allied compounds. Specific protein-binding measures are often used as assays in diagnostic assessments.	Plasma Protein Binding Capacity,Binding, Protein

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
