Concerted auto-regulation in yeast endosomal t-SNAREs.


In yeast, the assembly of the target (t)-SNAREs [Tlg2p/Tlg1p,Vti1p] and [Pep12p/Tlg1p,Vti1p] with the vesicular (v)-SNARE Snc2p promotes endocytic fusion. Here, selected mutations and truncations of SNARE proteins were tested in an in vitro fusion assay to identify potential regulatory regions in these proteins, and two distinct regions were found. The… (More)
