Functional studies on a novel, brain-specific, Golgi ATP-binding protein in membrane trafficking. In cells specialised for communication such as neurones, protein transport constitutes a large part of total cellular activity. A primary pathway in protein transport is trafficking from the Golgi apparatus to the cell membrane; materials destined for the cell membrane and secretion are sorted, packed and transported from the Golgi apparatus.

In cells specialised for communication such as neurones, protein transport constitutes a large part of total cellular activity. A primary pathway in protein transport is trafficking from the Golgi apparatus to the cell membrane; materials destined for the cell membrane and secretion are sorted, packed and transported from the Golgi apparatus. However, the mechanisms underlying these processes at the Golgi remain largely unknown. We have recently cloned a novel ATP-binding protein specifically expressed at the Golgi apparatus in human brain, and hypothesise that this protein regulates Golgi protein trafficking by interacting with two other molecules, dynamin and calcium, during cell secretion.Read moreRead less
