ABSTRACT:
The invention relates to the field of proteins, more specifically to those proteins that are located on the surface of the cell. The invention, amongst others, provides an inhibitor or pharmaceutical composition that is capable of inhibiting down-regulation of a cell surface receptor. The invention provides a method to control or up-regulate hormone activity by using inhibitors or reagents that modify down-regulation of a protein. The invention further provides a method to control or up-regulate protein activity wherein ligand-induced receptor uptake and/or degradation by endocytosis of a receptor is inhibited, preferably by inhibiting the ubiquitin/proteasome system.
