Resumen de TRAPPing Rab18 in lipid droplets
Francesca Zappa, Rossella Venditti, Maria Antonietta De Matteis
A number of membrane trafficking components are associated with lipid droplets (LDs) and/or are involved in their biogenesis. In this issue of The EMBO Journal, Li et al (2017) show that the mammalian TRAPPII (TRAnsport Protein Particle) complex acts as an LD‐associated GEF for Rab18, thereby regulating LD homeostasis.
