CERT:ceramide [ER] => ceramide [Golgi] + CERT [ER]
Species Homo sapiens
‚??CERT‚?? (ceramide transfer protein), associated with the cytosolic face of the endoplasmic reticulum (ER) in a complex with VAPA or VAPB (VAMP-associated proteins A or B) (Kawano et al. 2006) and PPM1L (protein phosphatase 1-like) (Saito et al. 2008), can bridge the gap between the ER and the Golgi apparatus via its PH domain and transfer a molecule of ceramide extracted from the ER membrane to the Golgi (Hanada et al. 2003; Saito et al. 2008). ‚??CERT‚??-mediated ceramide transfer is positively regulated by OSBP (oxysterol binding protein), by an unknown mechanism (Perry and Ridgway 2006).
