Traffic COPs of the Early Secretory Pathway

Abstract excerpt

Intracellular transport between the endoplasmic reticulum and Golgi compartments is mediated by coat protein complexes (COPI and COPII) that form transport vesicles and collect the desired set of cargo. Although the COPI and COPII coats are molecularly distinct, a number of mechanistic parallels appear to be emerging, most notably a general role for small guanine triphosphatases in co-ordinating coat assembly...
