July 6th, 2009. Progenra licenses UBL-CHOP reporter assay platform (formerly known as IsoPRO) to LifeSensors, Inc. Progenra's proprietary Ub-CHOP deubiquitylation assay is unique in that deubiquitylation liberates a reporter enzyme. Upon liberation, the reporter enzyme acts on its substrate, designed to yield a fluorescent product. Progenra has licensed the CHOP reporter technology to LifeSensors, Inc. Attachment of different reporters to the C-terminus of ubiquitin enables Progenra's technology to mimic most closely the physiological ubiquitylated DUB substrates. This feature of Progenra's platform is single-handedly responsible for the discovery of novel and selective molecules that target DUBs. CHOP is superior to off the shelf assay technologies, which measure the cleavage of a small molecule from a protein and thus do not probe all of the structural features of DUBs, which in nature cleave fusions of two large proteins. Thus, the chemical space discovered by such assays has been limited, as demonstrated by the lack of selective compounds reported. Currently, two different CHOP reporters are available, CHOP1 (PLA2) and CHOP2, via LifeSensors Inc.
