Our current focus is on molecular mechanisms of protein and lipid trafficking between the endoplasmic reticulum (ER) and the Golgi complex in. Several of the genes involved in this process have been identified and their function may be assessed in cell-free assays that reproduce transport. Through a combined genetic and biochemical approach, the mechanisms underlying secretory cargo selection and vesicle budding from the ER as well as vesicle targeting and fusion with the Golgi complex are under study. This intracellular transport step is essential for cellular function and our studies are basic for understanding numerous health related issues including cholesterol regulation, cystic fibrosis and diabetes.
The C-terminus of the cargo receptor Erv14 affects COPII vesicle formation and cargo delivery.
Twenty-five years after coat protein complex II.
Molecular dissection of the Erv41-Erv46 retrograde receptor reveals a conserved cysteine-rich region in Erv46 required for retrieval activity.
Conserved juxtamembrane domains in the yeast golgin Coy1 drive assembly of a megadalton-sized complex and mediate binding to tethering and SNARE proteins.
Lysophospholipids Facilitate COPII Vesicle Formation.
The Golgin protein Coy1 functions in intra-Golgi retrograde transport and interacts with the COG complex and Golgi SNAREs.
Cargo Capture and Bulk Flow in the Early Secretory Pathway.
Overexpression of Sly41 suppresses COPII vesicle-tethering deficiencies by elevating intracellular calcium levels.
