Ubc13, Bend, UbcD3
ubiquitin-conjugating enzyme that functions as a developmental switch that permits the transition from axonal growth and incipient synapse formation to synaptic growth and maturation - required in the IMD immune response signaling pathway for IKK activation leading to NFkappaB activation

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.
Tissue-specific extension of 3' UTRs observed during later stages (FBrf0218523, FBrf0219848); all variants may not be annotated
Low-frequency RNA-Seq exon junction(s) not annotated.
Annotated transcripts do not represent all supported alternative splices within 5' UTR.

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).

Please Note FlyBase no longer curates genomic clone accessions so this list may not be complete
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.
ben does not seem to be required for nascent synapse formation but rather plays a role in synaptic growth and maturation.
ben functions as a novel developmental switch that permits the transition from axonal growth and incipient synapse formation to synaptic growth and maturation in the central nervous system.

Mutants have pleiotropic phenotypes affecting thoracic muscle patterning, pupal mortality and post-eclosion mortality.
Mutations in ben cause a disruption in the recognition event leading to synapse formation between the giant fibre (GF) and the tergotrochanteral jump muscle motorneuron (TTMmn) giving rise to the GF phenotype. Also mutants exhibit morphological abnormalities within the visual system. Results suggest a role for ben for ubiquitin-mediated protein modification in nervous system development, including the regulation of synaptic connectivity.
Adults have an aberrant startle response; they do not jump when presented with a lights-off stimulus. The cervical giant fiber, a brain neuron, has abnormal morphology. The normal giant fiber terminates in the thorax at a synapse onto the motoneuron innervating the tergo-trochanteral (TT) muscle (= jump muscle). In ben, this synapse is abnormal or absent. The normal lateral bend of the giant fiber toward the TT motoneuron in the mesothoracic neuromere is absent; the axon usually terminates at the midline with fine branches extending from its tip. Latency of response of the TT muscle to stimulation of the giant fiber is abnormally long, and muscles cannot follow stimulation at rates above 5 Hz. Rhabdomeres of the photoreceptor cells in the ommatidia heart shaped in cross-section with indentation centrally oriented rather than round as is normal. Furthermore, the axons from photoreceptor cells R7 and R8 fail to make the right-angle turn into the optic medulla after traversing the lamina. ben flies choose visible over ultraviolet wave lengths whereas wild-type flies make the opposite choice.
Less than 25% ben flies show abnormalities in the dorsal attachment of the tergotrochantral muscle.
Behavioural data suggests antennal and maxillary basiconic sensilla may be important receptors for short chain alcohols and organic acids but less crucial for acetates, aldehydes and ketones.
Mutations have a defect in the pathway between the giant fibre and jump muscle, the giant fiber fails to make a bend which would normally bring it into proximity with the jump muscle motoneuron.
Mutations interrupt one neural connection in the giant fibre pathway that mediates the jump/flight escape response.
Mutations disrupt the synaptic transmission between the giant fibre (GF) system and the tergotrochanteral muscle (TTM, jumping muscle) motor neuron.
Mutation in ben deletes one of the processes of the giant fibre leaving the other portions functionally unaltered.
