Membrane traffic pathways between these organelles play key roles in transporting protein and lipid cargo. Traditionally, they are subdivided into the anterograde or secretory pathway and the endocytic pathway...

...Vasanth R. Singan; Kenan Handzic; Jeremy C.

Indeed, both endocytosis and exocytosis contribute to stabilizing the intercellular bridge that connects the daughter cells and to the final...

... that has been instrumental in deciphering the molecular principles of membrane traffic at the Golgi. BFA targets a low-affinity Arf–Sec7 intermediate of the exchange reaction. It binds at the Arf-GDP/Sec7 interface, thus freezing the complex in an abortive conformation that cannot proceed to nucleotide...
