sting, stellate-interacting gene
related to eukaryotic translation initiation factor 2C - involved in post-transcriptional gene silencing - a general regulator of maternal mRNAs - along with piRNAs plays a key developmental role in the embryo through decay and localization of mRNAs encoding germ cell determinants.

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

Component of the ping-pong piRNA processing (4P) complex consisting of krimp, aub and AGO3 (PubMed:26295961, PubMed:34210982). Interacts (via N-terminus when symmetrically dimethylated on arginine residues) with krimp (via tudor domain); this interaction requires methylation of at least one N-terminal arginie residue (PubMed:26295961, PubMed:34210982). Interacts with vas and AGO3 (PubMed:18590813, PubMed:19959991). May form part of a piRNA processing complex consisting of tud, aub and AGO3 (PubMed:19959991). Interacts (when symmetrically dimethylated on arginine residues) with tud; methylation and/or interaction requires association with piRNA (PubMed:18590813, PubMed:19926723, PubMed:19959991, PubMed:20713507, PubMed:34210982). Interacts (via N-terminus and when associated with piRNA) with csul/PRMT5; the interaction recruits the PRMT5 methylosome complex to modify N-terminal arginines by symmetrical dimethylation but involves residues other than the arginines to be modified (PubMed:34210982). Forms a complex with smg, twin, AGO3, nanos mRNA and piRNAs that targets the nanos 3'-untranslated region, in early embryos (PubMed:20953170). Interacts with nanos mRNA and rump (in an RNA-dependent manner) (PubMed:20937269). Interacts with papi and vret (PubMed:21447556, PubMed:21831924). Interacts with me31B (PubMed:28945271).
Symmetrical dimethylation of arginines (sDMA) on Arg-11, Arg-13 and/or Arg-15 by csul/PRMT5/DART5, is required for binding to tud, localization to the pole plasm and association with the correct piRNAs (PubMed:19377467, PubMed:19926723, PubMed:19959991, PubMed:20713507, PubMed:26212455, PubMed:34210982). SDMA on Arg-11, Arg-13, Arg-15 and/or Arg-17 is required for binding to krimp and stable recruitment to subregions of the nuage (PubMed:26295961, PubMed:34210982). Methylation state does not affect protein stability (PubMed:34210982). SDMA plays an important role in ping-pong amplification of piRNAs and is essential for function in vivo (PubMed:34210982). Methylation state functions as an indicator of its piRNA binding state (PubMed:34210982). PiRNA binding promotes sDMA modification; piRNA binding induces a conformational change that exposes the N-terminal arginines, making them available to the methylosome complex (PubMed:34210982).

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).
osk transcripts are detected at high levels in the germarium, at low levels during mid-oogenesis, and then at high levels in nurse cells and the ooctye from about stage S6 of oogenesis.
aub transcripts are detected in testis and ovary RNA on northerns and appear to accumulate exclusively in the gonads.

For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.
aub mutations act as genetic enhancers of Segregation Distorter. This effect is still seen when aub mutations are targeted (by homologous recombination) to the Dp(2;2)RanGAPSD chromosome, indicating that the effect of aub mutations is not specific to the target Rsp-bearing chromosome.
aub protein exhibits Slicer activity in vitro.
aub is required for maintenance of long-distance chromosomal interactions between endogenous PcG target loci.
aub is required for the accumulation of repeat-associated small interfering RNAs (rasiRNAs).
aub mutants block RNAi activation which normally occurs during egg maturation.
Mutations at the aub locus cause defects in midoogenesis.
Mutant alleles are female sterile, laying spindle shaped eggs with defective dorsal appendages; if fertilised the embryos show a posterior group phenotype.
