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 [...]

Ubiquitin-conjugating enzyme variant 1A (Uev1A) encodes a conserved protein that contributes to ubiquitin conjugating enzyme activity, but not catalytically, since it lacks the conserved cysteine residue essential for ubiquitin conjugation. It regulates genomic integrity, IMD pathway-mediated innate immunity, JNK-pathway mediated cell death and tumor invasion.

Ubiquitin-5E, isoform A; Protein tag; ubiquitin protein ligase binding. It is involved in the biological process described with: ubiquitin-dependent protein catabolic process; protein ubiquitination; modification-dependent protein catabolic process; cellular protein modification process.

Polyubiquitin; 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 degradatio [...]

Nedd8-activating enzyme E1 catalytic subunit; Catalytic subunit of the dimeric Uba3-APP-BP1 E1 enzyme. E1 activates Nedd8 by first adenylating its C-terminal glycine residue with ATP, thereafter linking this residue to the side chain of the catalytic cysteine, yielding a Nedd8-Uba3 thioester and free AMP. E1 finally transfers Nedd8 to the catalytic cysteine of UbcE2M. Required for Cul1 and Cul3 neddylation. Negatively regulates full-length ci stability and hedgehog signaling.

Ubiquitin-like activating enzyme 5 (Uba5) encodes a member of the E1-like ubiquitin-activating enzyme family. It activates the protein encoded by Ufm1, and acts as a key factor in the ufmylation process. It is involved in ATP binding, catalytic activity, cofactor binding, metal ion binding, nucleotide binding and oxidoreductase activity.

RE63412p; Ubiquitin-protein transferase activity; ubiquitin conjugating enzyme activity. It is involved in the biological process described with: ubiquitin-dependent protein catabolic process; protein polyubiquitination; proteasome-mediated ubiquitin-dependent protein catabolic process; Belongs to the ubiquitin-conjugating enzyme family.

Autophagy-related 7 (Atg7) encodes an E1-type ligase for the autophagic ubiquitin-like proteins encoded by Atg8a and Atg12. Its roles include autophagosome formation, maintaining neuromuscular function and normal lifespan.
