E3 ubiquitin-ligase essential for neuronal development - mutants display a lower rate of spontaneous neurotransmitter release due to failures at the pre-synaptic side - evoked release in Ari-1 mutants was enhanced in a Ca(2+) dependent manner without modifications in the number of active zones, indicating that the probability of release per synapse is increased in these mutants - regulates myonuclear organization together with Parkin and is associated with aortic aneurysms

Can form homodimers (PubMed:10880484, PubMed:29689197). Interacts (via RING-type 1 zinc finger) with Ubc10 (PubMed:10880484, PubMed:29689197). Interacts with the LINC complex member koi (PubMed:29689197). Interacts with park (PubMed:29689197). Interacts with ari-2 (PubMed:29689197). Specifically interacts with isoform ECR-A of EcR (PubMed:21900267).
Autophosphorylated.
Members of the RBR family are atypical E3 ligases. They interact with E2 conjugating enzymes such as Ubc10 and function like HECT-type E3 enzymes: they bind E2s via the first RING-type zinc finger, but require an obligate trans-thiolation step during the ubiquitin transfer, requiring a conserved active site Cys residue in the second RING-type zinc finger. The active site probably forms a thioester intermediate with ubiquitin taken from the active-site cysteine of the E2 before ultimately transferring it to a Lys residue on the substrate.

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).
Although ari-1 protein is detected mainly in the cytoplasm in Western blots of nuclear vs. cytoplasm enriched fractions, it does contain a putative nuclear localization signal.

Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see JBrowse for alignment of the cDNAs and ESTs to the gene model.
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.

The name "ariadne" refers to the loss of clues to find the correct path of axonal projection, and it evokes the Greek myth of the thread that Ariadne gave to Theseus to find his way in the Minotaur's labyrinth.
