NTMC2T5: a newly identified lipid transfer proteins at ER-chloroplast contact sites involved in development and stress response.

Abstract

In plants, fatty acid synthesis takes place at chloroplasts, and they are assembled into glycerolipids and sphingolipids at the endoplasmic reticulum (ER). Then, the newly ER synthetized lipids are sent back to the chloroplast to form part of their membranes. Since, no vesicular transport has been described between these two organelles, lipid transport might be mediated by lipid transport proteins (LTP) via a non-vesicular pathway.
