• plasma membrane
  • I show that munc 18-1 plays a vital role in binding to a closed-form of syntaxin 1a, keeping syntaxin 1a inactive and permitting its trafficking to the plasma membrane. (bl.uk)
  • I demonstrate that in the absence of munc 18-1, syntaxin 1a and SNAP-25 can readily interact in the Golgi complex, forming reactive SNARE complexes that fail to traffic to plasma membrane. (bl.uk)
  • Munc 18-1 has a vital regulatory role in preventing the formation of the binary complex between syntaxin 1a and SNAP-25 before the proteins reach their target destination of the plasma membrane. (bl.uk)
  • Upon delivery to the plasma membrane that t-SNAREs have been shown to form cholesterol dependent clusters in several cell types of between 60-7509 nm. (bl.uk)
  • Here I present evidence to show that once at the plasma membrane syntaxin 1a and SNAP-25 are concentrated in clusters of high local concentration that co-localise in neuroendocrine cells. (bl.uk)
  • Interestingly, despite reducing the affinity of SNAP-25 for syntaxin 1a using mutagenesis, these proteins still co-cluster and interact on the plasma membrane. (bl.uk)
  • The Golgi apparatus has long been suggested to be important for directing secretion to specific sites on the plasma membrane in response to extracellular signaling events. (ox.ac.uk)
