Subnuclear Bodies

Our laboratory studies the organisation of the cell nucleus, using fluorescently-tagged proteins and antibodies to "map" specific regions and structures. We are also purifying many of these structures in order to identify as many of their protein components as possible via proteomic approaches, which will give us important clues to the functions of these structures within the cell.

Many complicated cellular functions are carried out in the nucleus, and the substructures shown below are known in some cases to be sites where these functions actually occur, and in other cases to be "storage depots" for particular proteins required by these processes. By keeping the proteins in particular regions of the nucleus, they can be recruited quickly as needed.
