single pass transmembrane protein expressed on the surface of fusion competent myoblasts - essential for fusion of embryonic myoblasts - contributes to formation and function of the nephrocyte diaphragm and cell sorting within the developing ommatidia
AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

Expression of sns is observed in two bands in the fusion-competent myoblasts of the somatic and visceral mesoderm, a dorsal band corresponding to the fusion-competent myoblasts of the visceral mesoderm and a ventral band corresponding to the fusion-competent myoblasts of the somatic mesoderm.
sns protein is enriched at the cell membrane. The protein localizes to discrete sites in the membrane as muscle founder cell fusion progresses, and amounts of the protein decline during the process.
sns protein is localized to regions of cell-cell contact in mononucleate embryonic garland cells and binucleate embryonic/larval garland cells; distribution is also observed in in intracellular and cell surface puncta. kirre protein is partially colocalized with sns protein. sns protein is expressed in garland cells at all larval stages; immuno-EM reveals sns protein to be localized to the nephrocyte diaphragm of larval garland cells in second and third instar larvae.

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 GBrowse 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.
RNAi generated by PCR using primers directed to this gene causes a cell growth and viability phenotype when assayed in Kc167 and S2R+ cells.
snsis required for the formation of syncytia within the visceral musculature of the midgut.
