HB007
Based on 1 Customer Validation
HB007 is a SUMO1 molecular glue degrader targeting CAPRIN1 and FBXO42. HB007 selectively binds CAPRIN1 to induce CAPRIN1-FBXO42 interaction, recruits SUMO1 to the CAPRIN1-CUL1-FBXO42 E3 ligase complex, and drives SUMO1 ubiquitination and degradation without affecting SUMO2/3. HB007 induces TCF4 deSUMOylation and proteasomal degradation to inhibit StarD7 transcriptional activity, reduces StarD7 mRNA and protein levels, and triggers ER stress and ROS production. HB007 can be used for the research of brain cancer, breast cancer, colon cancer, lung cancer.
