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).

fng transcript is expressed 4-5 polar follicle cell precursor cells in stage 1-4 egg chambers, and later in the 2 polar cells that emerge from the prepolar group.
fng transcript is expressed in follicle cells starting in germarium region 2b. Expression is detected in anterior and posterior follicle cells in stage S2-S4, in all follicle cells in stage S5, in anterior and posterior polar follicle cells in stage S6-S9. At stage S10, expression is detected in all follicle cells except anterior-dorsal follicle cells.
fng is first detected in the wing disc in second instar larvae where it is restricted to the dorsal region of the disc. Expression remains in the dorsal part of the wing disc through the first half of the third instar after which some weak expression begins to appear in ventral regions outside of the wing pouch. In addition, fng expression is lost in some regions that will give rise to the notum. By the end of third instar, expression is lost in some dorsal regions within the wing pouch and becomes strong in proximal regions of the ventral wing.
Epitope-tagged fng protein localizes to the Golgi apparatus.

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.
fng seems to function in peripodial cells during eye development.
fng does not exert its effect outside the cell, but rather acts in the golgi apparatus, apparently as a glycosyltransferase.
fng is essential in oogenesis for the proper formation of the egg chamber and for epithelial morphogenesis.
fng encodes a boundary-specific cell-signalling molecule that is responsible for dorsal-ventral cell interactions during wing development.
