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 [...]

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.

Cullin family protein binding. It is involved in the biological process described with: SCF-dependent proteasomal ubiquitin-dependent protein catabolic process; ubiquitin-dependent protein catabolic process; Belongs to the SKP1 family.

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 [...]

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 [...]

Mitochondrial import inner membrane translocase subunit Tim13; Mitochondrial intermembrane chaperone that participates in the import and insertion of some multi-pass transmembrane proteins into the mitochondrial inner membrane. Also required for the transfer of beta-barrel precursors from the TOM complex to the sorting and assembly machinery (SAM complex) of the outer membrane. Acts as a chaperone-like protein that protects the hydrophobic precursors from aggregation and guide them through the mitochondrial intermembrane space. The Tim8- Tim13 complex mediates the import of some protei [...]

E3 ubiquitin-protein ligase Su(dx); E3 ubiquitin-protein ligase which accepts ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to targeted substrates. Down-regulates Notch/N signaling pathway, probably by promoting Notch ubiquitination, endocytosis and degradation. Involved in wing growth and leg joint formation.

Acylphosphatase-1; Acylphosphatase activity.
