Dimeric pleckstrin homology domain-containing family A member 8 (PLEKHA8, FAPP2) controls the transfer of GlcCer from the cis-Golgi to the trans-Golgi membrane. PLEKHA8 transport depends on binding to phosphatidylinositol 4-phosphate (PtdIns4P) and the small GTPase ARF1 (Godi et al., 2004; Vieira et al., 2005; D'Angelo et al., 2007; reviewed by Yamaji & Hanada, 2015). PLEKHA8 complex also forms tubules from membrane sheets. GlcCer reaches the plasma membrane via non-vesicular transport from the trans-Golgi, i.e., using tubular structures (Cao et al. 2009).
