27. an Arf1-GBF1-Brefeldin A complex is formed and has a longer residence time on Golgi membranes than GBF1 or Arf1 alone PMID: 15616190
28. A continuous cycle of recruitment and dissociation of GBF1 to membranes is required for sustained ARF activation and COP I recruitment that underlies ER-Golgi traffic. PMID: 15813748
29. GBF1 is recruited to the endogenous IRF-9 promoter, and interacts with C/EBP-beta, IL-1, and IL-6 PMID: 16318580
30. These observations strongly suggest that GBF1 regulates COPI membrane recruitment in the early secretory pathway. PMID: 16926190
31. Two different poliovirus proteins independently recruit different Arf GEFs (GBF1 and BIG1/2) to membranes as part of cellular pathways utilized by the virus to form its membranous replication complex. PMID: 17079330
32. analysis of the binding domain in GBF1 showed that the extreme N terminus, the dimerization/cyclophilin binding domain, and the homology upstream of Sec7 domain are required for the interaction with coxsackievirus protein 3A PMID: 17329336
33. These data support a model where Rab1b-GTP induces GBF1 recruitment at the ERES interface and at the Golgi complex where it is required for COPII/COPI exchange or COPI vesicle formation, respectively. PMID: 17429068
