High impact information on UBE2E1

  • Accordingly, UbcH6, RNF20/40, and the hPAF complex are recruited to transcriptionally active genes in vivo [1].
  • In in vitro assays site 2 polyubiquitylates the E2 enzymes UbcH5a and UbcH6 but not other (e.g., UbcH7) enzymes [2].
  • In this article, we show that ectopic expression of dominant negative UbcH5a carrying the substitution C85A delayed or blocked the degradation of PML and Sp100 and dispersal of ND10 whereas ectopic expression of wild-type UbcH5a or dominant negative UbcH6 and UbcH7 carrying the substitutions C131A and C86A, respectively, had no effect [2].
  • Here, we present evidences indicating that RING105, a novel conserved RING-finger protein with a PA (protease-associated) domain and a PEST sequence, is a ubiquitin ligase for TSSC5 that can function in concert with the ubiquitin-conjugating enzyme UbcH6 [3].
  • Tumor suppressor candidate TSSC5 is regulated by UbcH6 and a novel ubiquitin ligase RING105 [3].

Biological context of UBE2E1


Other interactions of UBE2E1

  • We isolated ISG15-modified and unmodified UbcH6 proteins, and analyzed their abilities to form thioester intermediates with ubiquitin [4].
  • The changes in H2B ubiquitination did not fully coincide with concurrent changes in the nuclear levels of the ubiquitin-conjugating enzymes Rad6 and UbcH6 [5].
  • Recombinant ARD1 (amino acids 1-574) or its RING finger domain (amino acids 1-110) produced polyubiquitylated proteins when incubated in vitro with a mammalian E1, an E2 enzyme (UbcH6 or UbcH5a, -5b, or -5c), ATP, and ubiquitin [6].
  • WSSV222 exhibits RING-H2-dependent E3 ligase activity in vitro in the presence of the specific conjugating enzyme UbcH6 [7].
