Summary: The protein encoded by this gene is a member of the ubiquitin-conjugating enzyme family. Ubiquitin-conjugating enzyme catalyzes the covalent attachment of ubiquitin to other proteins. This protein is a part of the large multiprotein complex, which is required for ubiquitin-mediated degradation of cell cycle G1 regulators, and for the initiation of DNA replication.

Targeting CDC34 E2 ubiquitin conjugating enzyme for lung cancer therapy.
Title: Targeting CDC34 E2 ubiquitin conjugating enzyme for lung cancer therapy.
Systematic identification of CDC34 that functions to stabilize EGFR and promote lung carcinogenesis.
Title: Systematic identification of CDC34 that functions to stabilize EGFR and promote lung carcinogenesis.
UBE2R2 alone had negligible ubiquitylation activity at physiological concentrations and the ablation of UBE2R1/2 had no effect on the stability of SCF substrates in cells. A genome-wide CRISPR screen revealed that an additional E2 enzyme, UBE2G1, buffers against the loss of UBE2R1/2.
Title: Robust cullin-RING ligase function is established by a multiplicity of poly-ubiquitylation pathways.
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
Title: The Catalytically Inactive Mutation of the Ubiquitin-Conjugating Enzyme CDC34 Affects its Stability and Cell Proliferation.
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.
Title: Mechanism of Lysine 48 Selectivity during Polyubiquitin Chain Formation by the Ube2R1/2 Ubiquitin-Conjugating Enzyme.
ubiquitin binding by the acidic loops of Ube2g1 and Ube2r1 enzymes distinguishes their Lys-48-ubiquitylation activities
Title: Differential ubiquitin binding by the acidic loops of Ube2g1 and Ube2r1 enzymes distinguishes their Lys-48-ubiquitylation activities.
We discuss how these results can explain the rapid association of Cdc34 and SCF.
Title: Ubiquitin-conjugating enzyme Cdc34 and ubiquitin ligase Skp1-cullin-F-box ligase (SCF) interact through multiple conformations.
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
Title: Multimodal mechanism of action for the Cdc34 acidic loop: a case study for why ubiquitin-conjugating enzymes have loops and tails.
These data suggest that FBXO15 and Ube2r1 regulate P-gp expression through the ubiquitin-proteasome pathway.
Title: FBXO15 regulates P-glycoprotein/ABCB1 expression through the ubiquitin--proteasome pathway in cancer cells.
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.
Title: Ectopic over-expression of tristetraprolin in human cancer cells promotes biogenesis of let-7 by down-regulation of Lin28.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
