UBCH8 Ubiquitin E2 Enzyme is Also the E2 Enzyme for ISG15, an Interferon Alpha/Beta Induced Ubiquitin-Like Protein.

摘要

The present invention relates to compositions and methods for the modulation of both ubiquitin and ubiquitin-like protein mediated modification and degradation of target proteins that includes the steps of contacting the compound with an Ubiquitin-like protein E2 enzyme and an E1 enzyme containing an ISG15 protein and an E1 containing ubiquitin and detecting the effect of the compound on the interaction between the Ubiquitin-like protein E2 enzyme and these two E1 enzymes, and the steps of contacting the compound with an Ubiquitin-like E2 enzyme containing an ISG15 protein or the same E2 enzyme containing ubiquitin and the E3 enymes that function with this E2 enzyme and detecting the effect of the compound on the interaction between these E2 and E3 enzymes.
