E3 ubiquitin-protein ligase bre-1; E3 ubiquitin-protein ligase that mediates monoubiquitination of 'Lys-117' of histone H2B. H2B 'Lys-117' ubiquitination gives a specific tag for epigenetic transcriptional activation and is also prerequisite for histone H3 'Lys-4' and 'Lys-79' methylation. Belongs to the BRE1 family.

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 [...]

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 [...]

Proliferating cell nuclear antigen; This protein is an auxiliary protein of DNA polymerase delta and is involved in the control of eukaryotic DNA replication by increasing the polymerase's processibility during elongation of the leading strand; Belongs to the PCNA family.

Ubiquitin conjugation factor E4 ufd-2; Acts as an E4 ubiquitin ligase mediating the assembly of polyubiquitin chains on substrates ubiquitinated by another E3 ubiquitin ligase. The elongation of preexisting ubiquitin chains preferentially targets ubiquitin 'Lys-29' and 'Lys-48' residues. Also functions as an E3 ligase in conjunction with specific E1 and E2 ligases. Probably by regulating protein ubiquitination at DNA damage repair sites, coordinates DNA double- strand-break repair and apoptosis in the germline. Required for germline apoptosis in response to DNA damage downstream of cep [...]

DNA polymerase.

Uncharacterized protein.

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 [...]

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 [...]
