WebJan 27, 2010 · The cytoskeleton carries out three broad functions: it spatially organizes the contents of the cell; it connects the cell physically and biochemically to the external environment; and it generates ... WebThe tube is formed from polymerized dimers of α-tubulin and β-tubulin, two globular proteins. These proteins form long chains that comprise the microtubuleʼs walls. The assembly is slow and occurs from the plus end, which is designated by a row of β-tubulin. Disassembly can occur rapidly at the plus end. (Note the minus end has a row of α-tubulin.)
WebCytoskeleton elements get their name from the fact that their diameter, 8 to 10 nm, is between those of microfilaments and microtubules. Figure 4.24 Intermediate filaments …
