Researchers at the National Cancer Institute (NCI) have developed an invention describing the binding domain (G2BD) for the ubiquitin-conjugating enzyme Ube2G2 in the gp78 ubiqutin ligase protein. The invention involves modulating the interaction between the gp78 protein and the conjugating enzyme Ube2G2. Interruption of this interaction will block degradation from the endoplasmic reticulum (ER), resulting in ER stress, unfolded protein response, and, ultimately, apoptosis in some cancer cells. The NCI seeks licensing and/or co-development partners for this invention.
