In this thesis, I characterized the association of Arf4•GDP with ER-Golgi intermediate compartment membranes. We confirmed that GDP-arrested Arf4 mutants associated with membranes irrespective of nature of tag or mutation. Recruitment appeared specific since loss of N-terminal myristoylation...

Characterization of GBF1, Arfs and COPI at the ER-Golgi intermediate compartment and mitotic Golgi clusters
DownloadFall 2009
Protein trafficking between the endoplasmic reticulum (ER) and Golgi complex is regulated by the activity of ADP-ribosylation factors (Arfs). Arf activation by guanine nucleotide exchange factors (GEFs) leads to the recruitment of the coatomer protein COPI and vesicle formation. By using...

The protein p53 is a key regulator of cellular response to a wide variety of stresses. In cancerous cells inhibitory regulators of the p53 protein such as MDM2 and MDMX are often overexpressed. In silico techniques could be used to inform the selection of interactions to target with novel drug...
