1. Importance of Endoplasmic reticulum to Golgi ceramide traffic to preserve muscle cell insulin signaling, CERT as a major actor in this process. PMID: 29759974
2. Data suggest that isolated PH and START domains of CERT interact with each other; START domain binds to PH domain at same site for PtdIns[4]P-binding; mutations disrupting PH-START interaction increase both PtdIns[4]P-binding affinity and ceramide transfer activity. (PH domain = N-terminal pleckstrin homology domain; START domain = StAR-related lipid transfer domain; PtdIns[4]P = phosphatidylinositol 4-phosphate) PMID: 28652409
3. Cells expressing mitoCERT import ceramides into mitochondria and undergo Bax-dependent apoptosis. PMID: 27888218

10. This review is focused on ceramide transfer protein (CERT) as a major regulator of ceramide flux in the cell. [review] PMID: 21707482
11. during cellular stress, disassembly of Golgi structure together with inactivation of CERT by caspases causes a reduction in ceramide trafficking and sphingomyelin synthesis, and could contribute to the cellular response to pro-apoptotic stress PMID: 22129459
12. the presence of IncD, CERT, VAPA/B, and potentially additional host and/or bacterial factors, at points of contact between the ER and the inclusion membrane provides a specialized microenvironment favorable to bacterial development. PMID: 21731489
13. We hypothesize that sphingomyelin acquired by CERT-dependent transport of ceramide and subsequent conversion to SM is necessary for C. trachomatis replication whereas SM acquired by GBF1-dependent pathway is essential for inclusion growth and stability. PMID: 21909260
14. GPBP directs myofibril formation through interaction with intracellular downstream effector 130-kDa GPBP-interacting protein PMID: 21832087

20. results indicate that CERT can mediate transfer of various types of ceramides that naturally exist and their close relatives PMID: 15596449
21. crypticity is a feature of the quaternary structure of two subsets of alpha3alpha4alpha5(IV) NC1 hexamers: autoantibody-reactive M-hexamers containing only monomer subunits and autoantibody-impenetrable D-hexamers composed of dimer and monomer subunits PMID: 15917228
22. Results identify a human-specific TNF-responsive transcriptional unit that locates GPBP in the signalling cascade of TNF and substantiates previous observations, which independently related TNF and GPBP with human autoimmunity. PMID: 16218959
23. A clinical evaluation of probands and their relatives of the five families carrying mutations in either the COL4A3 or the COL4A4 gene was carried out to underline the natural history of the autosomal recessive ATS. PMID: 16338941
24. Regulation of ceramide transport protein by oxysterol binding protein, and VAMP reveals a novel mechanism for ceramide transport and sphingophingomyelin synthesis in the Golgi apparatus. PMID: 16571669
25. The Golgi-targeting domain and endoplasmic reticulum-interacting FFAT amino acid motif of CERT spatially restrict the random ceramide transfer activity of the START domain in cells. PMID: 16895911
26. Data show that CERT receives multiple phosphorylations at a serine-repeat motif, a possibe site for casein kinase I, and that the phosphorylation down-regulates the ER-to-Golgi transport of ceramide. PMID: 17442665

28. GPBP regulates GBM collagen organization and its elevated expression causes dissociation and subsequent accumulation of IgA on the GBM. PMID: 17916599
29. CERT is a physiological substrate of PP2Cepsilon and that dephosphorylation of CERT by PP2Cepsilon may play an important role in the regulation of ceramide trafficking from the ER to the Golgi apparatus. PMID: 18165232
