AbstractSeveral intracellular proteins are involved in mediating vesicular transport of protein and lipid cargo from the endoplasmic reticulum (ER) to the Golgi apparatus (GA) in eukaryotic cells. Errors in membrane trafcking between ER and GA have been implicated in brain disorders [1, 7], showing that these processes are critical for neuronal biogenesis. An important protein in these processes is YIF1B, an intracellular 314-residue transmembrane protein. Hippocampal neurons from Yif1B knockout (KO) mice showed that Yif1B is implicated in anterograde trafcking and Golgi architecture , where depletion of Yif1b caused disorganization, fragmentation, and volume reduction of the GA in pyramidal neurons.
