Ubiquitin-conjugating enzyme E2-18 kDa; Ubiquitin-conjugating enzyme E2 that acts with the RBR family ligases LUBEL, ari-1 and possibly parkin. Accepts ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins (By similarity). Appears to be involved in the selective degradation of short-lived and abnormal proteins. Functions with ari-1 to control the subcellular localization and morphology of muscle nuclei (myonuclei) by regulating the protein levels and distribution of the LINC (LInker of Nucleoskeleton and Cytoskeleton) complex. Functions by mediating the [...]

Probable GDP-L-fucose synthase; Catalyzes the two-step NADP-dependent conversion of GDP-4- dehydro-6-deoxy-D-mannose to GDP-fucose, involving an epimerase and a reductase reaction; Belongs to the NAD(P)-dependent epimerase/dehydratase family. Fucose synthase subfamily.

Parkin (park) encodes an E3 ubiquitin ligase with a key role in protein ubiquitination. It is involved in mitochondrion organization, oxidative stress and locomotion; Belongs to the RBR family. Parkin subfamily.

Ubiquitin-40S ribosomal protein S27a; 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 involve [...]

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.

E3 ubiquitin-protein ligase ariadne-1; Atypical E3 ubiquitin-protein ligase, which catalyzes ubiquitination of target proteins together with ubiquitin-conjugating enzyme E2 Ubc10. Controls the subcellular localization and morphology of muscle nuclei (myonuclei) by regulating the protein levels and distribution of the LINC (LInker of Nucleoskeleton and Cytoskeleton) complex. Functions by mediating the monoubiquitination of the LINC complex subunit koi leading to its subsequent proteasomal degradation. Appears to function, at least partially redundantly, with the RBR E3 ligase family mem [...]

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 [...]

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.

Ubiquitin activating enzyme 1 (Uba1) encodes an E1 enzyme involved in protein ubiquitylation. It contributes to multiple processes including regulation of Ras-ERK signaling, autophagy, apoptosis and tissue growth; Belongs to the ubiquitin-activating E1 family.
