P27 UBIQUITINATION ASSAY AND METHODS OF USE

摘要

This invention relates to easy and reliable assays for the ubiquitination of p27. Because the assay can be performed as a plate capture assay, or as a homogenous time-resolved fluorescence resonance energy transfer assay, with defined, easily replicatable reaction conditions, it is particularly useful for high-throughput screening of, for example, a prospective anticancer agent. The invention provides methods to determine the amount of ubiquitination of p27, or of any protein, and use of the method to identify compounds that modulate the ubiquitination of p27, or any protein.
