Abstract
The present invention is based on the discovery of a composition that provides targeted ubiquitination. Specifically the composition contains a ubiquitin pathway protein binding moiety which recognizes a ubiquitin pathway protein and a targeting moiety which recognizes a target protein. In addition, the present invention provides libraries of compositions, where each composition contains a ubiquitin pathway protein binding moiety and a member of a molecular library. The libraries of the present invention can be used to identify proteins involved in a predetermined function of cells.
Claims9
A composition comprising:
- a) a ubiquitin pathway protein binding moiety that specifically binds to a ubiquitin protein ligase;
- and
- b) a target protein binding moiety covalently coupled to the ubiquitin pathway protein binding moiety of a), wherein the target protein binding moiety specifically binds to an estrogen receptor.
A composition comprising:
- a) a ubiquitin pathway protein binding moiety, wherein the binding moiety is selected from the group consisting of IkBalpha and an IkBalpha peptide that specifically binds to a ubiquitin protein ligase;
- and
- b) a target protein binding moiety covalently coupled to the ubiquitin pathway protein binding moiety of a), wherein the target protein binding moiety binds to an estrogen receptor.
A composition comprising:
