| Post Translational Modifications | Phosphorylation at Ser-209 is necessary and sufficient for the direct interaction of the phosphorylated FFAT motif with the MSP domain of MOSPD2, VAPA and VAPB and allows the tethering of two membranes that participates in the formation of ER-endosome contacts. Phosphorylation of the FFAT motif leads to conformation changes. Additional phosphorylations around the core FFAT motif (QFYSPPE) are not essential but strengthen the interaction with MOSPD2, VAPA and VAPB. Phosphorylation at Ser-209 of FFAT motif drives membrane tethering between the endoplasmic reticulum and late endosomes via interaction with VAPA and VAPB that in turn allows the efficient transport of sterol mediated by the START domain. |
| Function | Sterol-binding protein that mediates cholesterol transport from the endoplasmic reticulum to endosomes. The sterol transport mechanism is triggered by phosphorylation of FFAT motif that leads to membrane tethering between the endoplasmic reticulum and late endosomes via interaction with VAPA and VAPB. Acts as a lipid transfer protein that redirects sterol to the endosome at the expense of the cell membrane and favors membrane formation inside endosomes. May also mediate cholesterol transport between other membranes, such as mitochondria membrane or cell membrane. However, such results need additional experimental evidences.probably mainly mediates cholesterol transport from the endoplasmic reticulum to endosomes. Does not activate transcriptional cholesterol sensing. Able to bind other lipids, such as lutein, a xanthophyll carotenoids that form the macular pigment of the retina. |
