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).
Comment: body without gonads
Comment: presynaptic marker
Comment: observed at A1-7 ventral longitudinal muscle 3 and 4
Csp protein is enriched in the neuropil of the larval ventral ganglion, where synapses occur.
Csp protein is detected presynaptically at larval and adult neuromuscular junctions. Synaptic boutons are strongly stained. In the CNS, Synapse rich regions of the neuropil are stained, but the surrounding cell bodies are not. One isoform is detected predominantly in photoreceptor terminals but not at motor nerve terminals. Csp protein is thought to be associated with synaptic vesicles.

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.
monoclonal
Candidate stable intronic sequence RNA (sisRNA) identified within CDS of this gene.
The J-domain of Csp is important for minimising asynchronous release shortly after the evoked EJP.
The J-domain of Csp is important in maintaining normal Ca[2+] resting levels in synaptic terminals.
Mutations in Csp affect calcium secretion coupling of evoked exocytosis but not vesicle recycling.
Fluorescent Ca-sensitive dye, Ca Crimson, is used to monitor presynaptic Ca dynamics.
An analysis of the excitatory postsynaptic currents from depolarized motor nerve terminals leads to the conclusion that Csp protein is involved in neurotransmitter release and helps to synchronise evoked neurotransmitter release at nerve terminals.
A RNA helicase, member of the DEAD box protein family, is the adjacent transcript unit to Csp that expresses two RNA transcripts.
Csp expression pattern has been studied: MAB ab49 antibodies were used to screen cDNA expression libraries to identify clones coding for recognized protein fragments.
