- However, the use of mutant expression in the presence of endogenous protein left it unclear how the observed effects were related to the defect of vesicle docking in (M)unc18-1 knock-outs. (jneurosci.org)
- The membrane bound docking subcomplex includes several Pex proteins, Pex13p, 14p and 17p. (tcdb.org)
- Docking to the plasma membrane prepares vesicles for rapid release. (rupress.org)
- In contrast, we see that UNC-13, a docking factor for synaptic vesicles, is not essential for dense core vesicle docking. (rupress.org)
