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.

Activator of SUMO 1 (Aos1) encodes one of two subunits (along with the product of Uba2) of the heterodimeric SUMO activating enzyme.

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.

SUMO-activating enzyme subunit; Ubiquitin-like activating enzyme 2 (Uba2) encodes one of two subunits (along with the product of Aos1) of the heterodimeric SUMO activating enzyme. It contains the catalytic cysteine residue that first becomes adenylated using ATP and that then forms a thioester linkage to the C-terminal end of SUMO; 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.

ULP_PROTEASE domain-containing protein; SUMO-specific isopeptidase activity. It is involved in the biological process described with: protein desumoylation.

Degringolade, isoform A; Degringolade (dgrn) encodes a SUMO-Targeted ubiquitin ligase. During development it is required for Notch signaling and patterning. It contributes to transcriptional regulation, DNA repair, and cytoskeleton dynamics.

Ran GTPase-activating protein; GTPase activator for the nuclear Ras-related regulatory protein Ran, converting it to the putatively inactive GDP-bound state (By similarity). Trans-acting factor necessary for meiotic distortion. Distortion is only seen in individuals that carry the RanGAP tandem duplication and express a RanGAP truncated protein. Binding of truncated RanGAP product to the Responder(RSP) locus initiates events that lead to sperm dysfunction. During oogenesis, plays a role in the biogenesis of annulate lamellae containing nuclear pore complex components. Belongs to the RN [...]
