E3 ubiquitin-protein ligase ubr-1; E3 ubiquitin-protein ligase which is a component of the N-end rule pathway (By similarity). Recognizes and binds to proteins bearing specific N-terminal residues that are destabilizing according to the N- end rule, leading to their ubiquitination and subsequent degradation (By similarity). In complex with ced-3, required for the ced-3-mediated cleavage and subsequent degradation of the heterochronic protein lin-28 to regulate seam cell fate patterning during larval development. Negatively regulates glutamate metabolism through the aspartate aminotrans [...]

UBA_e1_C domain-containing protein; Belongs to the ubiquitin-activating E1 family.

Ubiquitin-conjugating enzyme E2 13; Involved in protein ubiquitination, but has no ubiquitin ligase activity on its own. The uev-1-ubc-13 heterodimers catalyze the synthesis of non-canonical 'Lys-63'-linked polyubiquitin chains. Involved in sorting Lys-63-linked polyubiquitinated maternal membrane proteins for degradation by targeting to multivesicular bodies. May be involved in the ubiquitination and growth of intracellular polyglutamine protein aggregates. May have a role in AMPA-type glutamate receptor trafficking in neurons.

UBiquitin Conjugating enzyme.

Ubiquitin-conjugating enzyme E2 variant 1; Involved in protein ubiquitination, but has no ubiquitin ligase activity on its own. The uev-1-ubc-13 heterodimer catalyzes the synthesis of non-canonical poly-ubiquitin chains that are linked through Lys-63. Involved in sorting Lys-63-linked polyubiquitinated maternal membrane proteins for degradation by targeting to multivesicular bodies. Required for glr-1-containing glutamate receptor trafficking in neurons. May have a role in synaptic transmission at motorneurons. May be involved in the ubiquitination and growth of intracellular polygluta [...]

Ubiquitin-related; Ubiquitin exists either covalently attached to another protein, or free (unanchored). When covalently bound, it is conjugated to target proteins via an isopeptide bond either as a monomer (monoubiquitin), a polymer linked via different Lys residues of the ubiquitin (polyubiquitin chains) or a linear polymer linked via the initiator Met of the ubiquitin (linear polyubiquitin chains). Polyubiquitin chains, when attached to a target protein, have different functions depending on the Lys residue of the ubiquitin that is linked: Lys-48-linked is involved in protein degrad [...]

RING-box protein 1; Component of the SCF (SKP1-CUL1-F-box protein) E3 ubiquitin ligase complex, which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Through the RING-type zinc finger, seems to recruit the E2 ubiquitination enzyme to the complex and brings it into close proximity to the substrate (By similarity). Essential for meiosis, mitotic chromosomal condensation and cytokinesis. Involved in histone H3 phosphorylation.

Ubiquitin-conjugating enzyme E2 25; Catalyzes the covalent attachment of ubiquitin to other proteins (Potential). Required for the maintenance of neuromuscular function.

Ubiquitin-60S ribosomal protein L40; [Ubiquitin]: exists either covalently attached to another protein, or free (unanchored). When covalently bound, it is conjugated to target proteins via an isopeptide bond either as a monomer (monoubiquitin), a polymer linked via different Lys residues of the ubiquitin (polyubiquitin chains) or a linear polymer linked via the initiator Met of the ubiquitin (linear polyubiquitin chains). Polyubiquitin chains, when attached to a target protein, have different functions depending on the Lys residue of the ubiquitin that is linked: Lys-48-linked is invol [...]
