GOLPH3 tunes up glycosphingolipid biosynthesis for cell growth.

Published in: The EMBO journal (2021)
Glycosphingolipids are a structurally diverse class of lipids that regulate plasma membrane protein function. Rizzo et al (2021) now show that GOLPH3 promotes intra-Golgi transport of several enzymes that function at branching points of sphingolipid biosynthesis. By regulating the cellular sphingolipidome, GOLPH3 promotes growth factor signaling and cell proliferation, which may explain its oncogenic properties.
