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 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.
Loss of nonC function impairs basal synaptic efficacy and reduces the fidelity of neurotransmission.
nonC facilitates gross neuromuscular junction synaptic morphological development, but does not appear to be required for maintenance of pre- and postsynaptic molecular specializations in individual boutons.
nonC is involved in regulation of the trafficking underlying synaptic vesicle pools.
nonC mutants exhibit impaired presynaptic function at the level of whole animal and single synaptic boutons.
Loss of nonC prevents the synaptic vesicle cycle from maintaining the rate required during periods of demand for high-frequency transmission.
Two nonsense alleles of Smg1 do not affect nonsense-mediated decay in D.melanogaster.
dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R+ cell morphology.
Mutants show resistance to cyromazine growth regulator.
Defective phototaxis and optomotor responses; no light-on or light-off transients in electroretinogram, probably due to defect in photoreceptor cells per se; abnormal orientation to spots in Y-maze test.
