Abstract:<div>Abstract<p>Speckle-type POZ protein (SPOP) is a substrate-binding adaptor of the CULLIN3/RING-box1 E3 ubiquitin ligase complex. SPOP is frequently mutated in prostate and endometrial cancers, whereas it is overexpressed in renal cell carcinoma (RCC). SPOP can mediate both degradable and nondegradable polyubiquitination of a number of substrates with diverse biological functions such as androgen receptor (AR), SRC-3, TRIM24, BRD4, PD-L1, 53BP1, GLP/G9a, c-Myc, SENP7, among others. Cancer-associ… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
