WebElongin (SIII) was initially identified and purified to homogeneity from rat liver nuclei ( 153) as a heterotrimeric complex of A, B, and C subunits with apparent molecular masses of ~ 110, ~ 18, and ~ 15 kDa. Subsequent biochemical studies have shown (1) that elongin A is the transcriptionally active subunit of elongin (SIII) ( 154) and ... WebMar 18, 1997 · The VHL protein (pVHL) has been shown to form a stable complex with elongin B and elongin C, two factors that stabilize and activate the transcription elongation factor elongin A. Here, Hs-CUL-2, a member of the recently identified multigene family, the cullins, is shown to specifically associate with the trimeric pVHL-elongin B-C (VBC) …
WebJul 18, 2000 · Elongin B, initially noted for its role as an elongin C chaperone , binds to elongin C through interactions between β-sheet regions . The binding of elongin B greatly enhanced the stabilization of both pVHL and elongin C (Fig. 4), demonstrating that interactions between these proteins serve to strengthen the entire pVHL/elongin BC … WebThe ubiquitination and degradation of HIF-1α are promoted by RACK1. RACK1 is an essential component of an O 2 /PHD/VHL-independent system for regulating HIF-1α stability through competition with HSP90 and recruitment of the Elongin-C/B ubiquitin ligase complex. Here we discuss how this system may be regulated.
