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).
Gene Group (FlyBase)
SUMO ACTIVATING ENZYMES -
SUMO activating enzymes are 'canonical' E1 enzymes that act as heterodimers to activate the ubiquitin-like protein SUMO for subsequent steps along the SUMO conjugation cascade. They perform three distinct chemical reactions: first, they bind ATP, magnesium and SUMO to catalyze formation of a high-energy acyl adenylate intermediate with subsequent release of pyrophosphate; second, an E1 catalytic cysteine attacks the SUMO-adenylate to catalyze formation of a high-energy thioester bond between the E1 and SUMO and release of the AMP product; finally, the E1-SUMO catalyzes transthioesterification to an E2 to form a high energy thioester-linked E2-SUMO product. (Adapted from PMID:28234446.)

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.

Testis-specificity index

The testis specificity index was calculated from modENCODE tissue expression data by Vedelek et al., 2018 to indicate the degree of testis enrichment compared to other tissues. Scores range from -2.52 (underrepresented) to 5.2 (very high testis bias).

Additional Descriptive Data

Maternal Aos1 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. 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. Aos1 transcripts are weakly expressed in spermatogonial cells at the tip region and remain detectable in the spermatocytes and spermatids.
