Abstract:
Syntaxin 16 (Syx16) is member of the soluble N-ethylmaleimide sensitive factor attachment protein receptor (SNARE) family of molecules that functions in membrane fusion in eukaryotic cells. A rather ubiquitously expressed, tail-anchored membrane protein localized mainly at the trans-Golgi network (TGN), it mediates primarily retrograde endosomal-TGN transport. In spite of its ubiquitous expression, Syx16 has specific and interesting roles in the physiology of specialized cells, including Glut4 dynamics, dendritic outgrowth-related membrane traffic, and cytokinesis. We discussed these physiological functions of Syx16 in the light of what is known of its subcellular localization, vesicular trafficking pathways involved, cognate SNARE partners and other interacting proteins. Further, we speculate on some possible pathophysiological roles of Syx16.

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...
