| Research Abstract |
CERT is a cytosolic protein that transports ceramide from the endoplasmic reticulum to the Golgi apparatus. The CERT-mediated transport of ceramide is accelerated by interaction between CERT and ER-resident membrane protein, VAP-A, but a regulatory mechanism for the interaction has not been determined. In this study, we demonstrated that phosphorylation at certain residue of CERT strengthened the interaction between CERT and VAP-A to facilitate ER-to-Golgi ceramide trafficking by CERT.
