Distinct roles for TANGO1S domains in maintaining ER-Golgi architecture

The endoplasmic reticulum (ER)-Golgi interface is a dynamic trafficking hub maintained in part by TANGO1, a scaffolding protein that coordinates proteins and membranes at ER exit sites (ERES). TANGO1 has two isoforms: TANGO1L, which has a lumenal SH3 domain, and TANGO1S, which la...

Identification of TMEM263 as an ER-resident protein that controls early stages of lipid droplet biogenesis

Abstract Cell and organismal growth is controlled not only by the availability of nutrients, but also the ability to dynamically sense and respond to changes in metabolic demand. We have identified a protein, TMEM263 (also known as C12orf23) as a mechanistic link between growth a...
