Lesswright (lwr) encodes Ubc9, a SUMO conjugating enzyme that accepts SUMO from the SUMO activating enzyme and hands it off to the SUMO conjugation target. It has documented biological functions in innate immunity, meiosis, and anterior patterning of the embryo.

Small ubiquitin-related modifier; Smt3 (smt3) encodes the only Drosophila SUMO family protein. It is required for embryonic patterning and mitosis. It may also have roles in wing patterning, Dpp signaling, and Ras/MAPK signaling. It localizes to the nucleus during interphase and to the kinetochores and midbodies during mitosis; Belongs to the ubiquitin family. SUMO subfamily.

Suppressor of variegation 2-10 (Su(var)2-10) encodes a member of the PIAS protein family that regulates chromosome structure and function. As a JAK/STAT pathway regulator, it contributes to eye formation and eye determination.

Nedd8-conjugating enzyme UbcE2M; Accepts the ubiquitin-like protein Nedd8 from the Uba3-APP- BP1 E1 complex and catalyzes its covalent attachment to other proteins. Required for Cul1 and Cul3 neddylation. Negatively regulates full- length ci stability and hedgehog signaling.

Uncharacterized protein CG4449; It is involved in the biological process described with: double-strand break repair via homologous recombination.

GH15225p; Ulp1 (Ulp1) encodes a cysteine protease that catalyzes both SUMO maturation and SUMO deconjugation. It localizes to the nucleoplasmic face of the nuclear pore complex. Ulp1 knockdown in S2 cells results in relocalization of SUMO from the nucleus to the cytoplasm.

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.

E3 SUMO-protein ligase RanBP2; E3 SUMO-protein ligase (By similarity). Component of the nuclear pore complex (NPC), a complex required for trafficking across the nuclear envelope. Required for nuclear import of nuclear localization signal (NLS)-containing proteins in an importin alpha/importin beta-dependent manner, but also for the nuclear import of specific proteins such as phosphorylated Mad or the sesquiterpenoid juvenile hormone receptor Met as part of the juvenile hormone signal transduction pathway. Plays a role in nuclear mRNA export by recruiting the mRNA transport complex com [...]

NEDD8; Ubiquitin-like protein which plays an important role in cell cycle control, embryogenesis and neurogenesis. Covalent attachment to its substrates requires prior activation by the E1 complex Uba3-Ula1 and linkage to the E2 enzyme UbcE2M. Attachment of Nedd8 to cullins activates their associated E3 ubiquitin ligase activity, and thus promotes polyubiquitination and proteasomal degradation of cyclins and other regulatory proteins.
