CDC34 Antibody

1. study finds that mutation of the catalytically active cysteine to serine (C93S) results in the reduced ubiquitination, increased stability, and attenuated degradation rate of CDC34; Through semi-quantitative proteomics, identified the CDC34-interacting proteins and discovered that the wild-type and mutant proteins have many differentially interacted proteins PMID: 29564676
2. Study shows that Ube2R1/2 forms a salt bridge interaction between a conserved Asp residue on Ube2R1/2 and acceptor ubiquitin residue Arg 54 and that perturbation of this interaction leads to the severe loss of UbeR2 activity. Results also provide new insight into how the Ube2R1/2 acidic loop may participate in catalysis. PMID: 27044868
3. ubiquitin binding by the acidic loops of Ube2g1 and Ube2r1 enzymes distinguishes their Lys-48-ubiquitylation activities PMID: 25471371
4. We discuss how these results can explain the rapid association of Cdc34 and SCF. PMID: 25425648
5. Here we have investigated how the acidic loop in human Cdc34 promotes ubiquitination, identifying two key molecular events during which the acidic loop exerts its influence PMID: 24129577
6. These data suggest that FBXO15 and Ube2r1 regulate P-gp expression through the ubiquitin-proteasome pathway. PMID: 23465077
7. Tristetraprolin promotes an increase in expression of mature let-7, which leads to the inhibition of let-7 target gene CDC34 expression and suppresses cell growth. PMID: 22210895
8. work provides the first structural details that show how the C-terminus of CDC34 might direct a thiolester-bound Ub to control polyubiquitin chain formation PMID: 21296085
9. the human Cdc34 carboxyl terminus contains a non-covalent ubiquitin binding activity that contributes to SCF-dependent ubiquitination PMID: 20353940
10. COP9 signalosome protects ubiquitin-conjugating enzyme 3 (UBC3/Cdc34) from beta-transducin repeat-containing protein (betaTrCP)-mediated degradation PMID: 20378537
11. determined that a ubiquitin (Ub) fused at I kappaB alpha K21 acts as a receptor, directing Cdc34 for rapid and efficient K48-linked Ub chain synthesis that depends on SCF(beta TrCP2) and the substrate's N terminus. PMID: 20347421
12. degraded by HSV-1 ICP0 while stabilizing cyclins D1 and D3 PMID: 14645576
13. antisense oligonucleotides targeting the human ubiquitin-conjugating enzyme Cdc34 downregulate its expression, inhibit the degradation of p27Kip1, and prevent cellular proliferation PMID: 15652359
14. although a Cdc34 mutant bearing a deletion of the C-terminal 36 amino acids (Cdc34 1-200) was efficiently charged with ubiquitin by E1, it was severely reduced for the ability to ubiquitinate p27(Kip1) in vitro compared to wildtype Cdc34 PMID: 16123592
15. Data suggest that the Skp1.CUL1.F-box-mediated polyubiquitination reaction may require the conversion of Cdc34 from an inactive monomer to a highly active dimeric form. PMID: 16210246
16. in vivo phosphorylation sites on budding yeast Cdc34 (yCdc34; Ser207 and Ser216) and human Cdc34 (hCdc34 Ser203, Ser222 and Ser231) to serine residues in the acidic tail domain, a region that is critical for Cdc34's cell cycle function PMID: 17461777
17. In tissue culture cells, Uba6 is required for charging a previously uncharacterized Uba6-specific E2 (Use1), whereas Ube1 is required for charging the cell-cycle E2s Cdc34A and Cdc34B PMID: 17597759
18. These findings support the hypothesis that human Cdc34 S95 and E108/E112 are required to position the donor ubiquitin optimally for catalysis, in a manner that might depend on E2 dimerization. PMID: 17698585
19. cisplatin increased ATF5 protein expression via preventing its ubiquitin-dependent degradation, which might be associated with its promoting the nucleus-to-cytoplasm translocation of E2 ubiquitin-conjugating enzyme Cdc34 PMID: 18458088
20. Cdc34 is a functional target of let-7 and that let-7 induces down-regulation of Cdc34, stabilization of the Wee1 kinase, and an increased fraction of cells in G(2)/M in primary fibroblasts. PMID: 19126550
21. The acidic tail of the Cdc34 ubiquitin-conjugating enzyme functions in both binding to and catalysis with ubiquitin ligase SCFCdc4. PMID: 19875449
22. Study shows that chain assembly by ubiquitin ligase SCF and ubiquitin-conjugating enzyme Cdc34 is facilitated by the unusual nature of Cdc34-SCF transactions: Cdc34 binds SCF with nanomolar affinity, nevertheless the complex is extremely dynamic. PMID: 19945379
