abstract = {The presence and function of microtubules within the
synaptic bouton has long been under investigation. In recent
years, evidence has accumulated that connects the synaptic
vesicle cluster to the local dynamics of microtubule ends.
Nonetheless, one question remains open, namely whether the
vesicles influence the availability of tubulin within the
synaptic compartment.An analysis of previously published
live imaging experiments indicates that tubulin is strongly
enriched in the synaptic vesicle cluster. To analyze the
vesicle-tubulin interaction directly, we isolated vesicles
from the mouse brain and imaged them together with
fluorescent tubulin in vitro. We found that soluble tubulin
is collected by synaptic vesicles in physiological buffers,
resulting in the formation of tubulin-rich regions (TRRs) on
the respective vesicle clusters.We conclude that the
synaptic vesicle cluster is indeed able to recruit soluble
tubulin.},
