Abstract:
NSF (N-ethylmaleimide sensitive factor) and its yeast counterpart Sec18 are highly conserved homohexameric proteins that play vital roles in eukaryotic membrane trafficking. Sec18 functions by disrupting SNARE complexes formed in cis, on the same membrane. However, the molecular mechanisms of this process are poorly understood, in large part due to the lack of selective, reversible inhibitors. A new study by Sparks et al. now reports a small molecule that appears to selectively inhibit Sec18 action in an in vitro assay. Their finding now paves the way to elucidate further details of Sec18-mediated SNARE priming.

SNAREs and Membrane Fusion
SNAREs exist in pairs that symmetrically interact and catalyze the fusion of the lipid bilayers in vesicle and target organelle. v-SNARE in the vesicle membrane are single polypeptide chains that bind to a complementary t-SNARE, composed of 2...

Flippase
Eukaryotic flippases are type-IV P-type ATPases or P4-ATPases belonging to P-type ATPase family proteins that are membrane-bound pumps involved in the ATP-mediated transport of ions and molecules across the membrane. Flippases flip specific phospholipids from the outer to the inner leaflet of a membrane. All P4-ATPases have one...
