Dictionary » T » Treadmilling



(Science: cell biology) name given to the proposed process in microtubules in which there is continual addition of subunits at one end and disassembly at the other, so that the tubule stays of constant length, but individual subunits move along.

Could in principle be used as a transport mechanism, although this is not currently favoured as a possibility. Has also been suggested for microfilaments.

"Treadmilling"? Is it in actin and microtubules?

Can anyone explain to me what "treadmilling" is? And can it occur in BOTH microtubules and actin? :? Very appreciative!
