Gene Summary
Small ubiquitin like modifier (Sumo) 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.

Gene Group (FlyBase)
SUMO PROTEINS -
Sumo is a highly conserved, approximately 90 amino acid ubiquitin-like protein that is conjugated to substrates through a cascade of E1 activating enzymes, E2 conjugating enzymes, and E3 ligases. Conjugation of Sumo to target proteins (sumoylation) regulates their activity, stability, subcellular localization, or macromolecular interactions. Sumoylation is reversible and is used to regulate many processes with central roles in development including signal transduction, the epigenetic control of transcription, and the development and function of the innate immune system. (Adapted from PMID:28234446 and PMID:32188601.)
Pathway (FlyBase)
Positive Regulators of Toll-NF-κB Signaling Pathway -
In Drosophila, the canonical Toll signaling pathway is initiated by the binding of a spatzle ligand to Toll (Tl) or a Toll-like receptor leading to the nuclear localization of the NF-κB (dl or Dif) transcription factor. Positive regulators of Toll-NF-κB Signaling lead to the increased nuclear accumulation of the NF-κB proteins and regulated expression of target genes. (Adapted from FBrf0091014 and FBrf0223077).
Positive Regulators of Hedgehog Signaling Pathway -
Positive regulators of hedgehog signaling up-regulate the pathway, resulting in the activation of transcription of hh-responsive genes.
Summary (Interactive Fly)

a low molecular weight protein modifier that is vital for multicellular development - over 140 SUMO conjugates have been identified in the early embryo including Dorsal, Tramtrack, Vestigial, SoxNeuro, Medea, Mod(mdg4) and CP190 and the bi-functional tRNA charging enzyme glutamylprolyl-tRNA synthetase

Model Confidence:
  • Very high (pLDDT > 90)
  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

Additional Descriptive Data

Maternal Sumo transcripts are distributed throughout the embryo until stage 10 and then decrease gradually. From stage 14 until the end of embryogenesis, transcripts are observed in the embryonic gonads in the pole cells. Sumo is also strongly expressed in the CNS. Within ovaries, transcripts are weakly detected in the germarium, are strongly expressed in stage S1-10 nurse cells and are weakly detected in the oocyte up until stage S10. Sumo transcripts are weakly expressed in spermatogonial cells at the tip region and remain detectable in the spermatocytes and spermatids.

The 1.5 and 2.5 kb Sumo transcripts are detected in embryos, larvae, and adults. The 1.5 kb transcript is most abundant in larvae.

        RNAi screen using dsRNA made from templates generated with primers directed against this gene causes defects in the formation of monastral bipolar spindles when assayed in S2 cells in the presence of Cdc27 dsRNA. This phenotype cannot be observed when the screen is performed without Cdc27 dsRNA.

        Expression is enriched in embryonic gonads.

        S2 cells treated with dsRNA generated against this gene show reduced phagocytosis of Candida albicans compared to untreated cells.

        dsRNA made from templates generated with primers directed against smt3 that is transfected into S2 treated with Listeria monocytogenes reveals smt3 to be involved in Listeria monocytogenes intracellular growth.

        RNAi generated by PCR using primers directed to this gene causes a cell growth and viability phenotype when assayed in Kc167 and S2R+ cells.

        smt3 plays a maternal role in A/P polarity and patterning.

        6 alleles of l(2)SH0182 recovered in a P-insertion screen.
