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.
polyclonal
Embryos injected with dsRNA made from templates generated with primers directed against this gene show late epithelial embryonic defect - these embryos die following profound defects in the development of the tracheal epithelial tubes.
Lac behaves as a homophilic cell adhesion molecule required to provide epithelial integrity to the tracheal tubes and to control tubular epithelium length.
Area matching Drosophila Lachesin gene, Acc. No. L13255.
Mutation in Lac alters tracheal tube size in embryos without affecting other aspects of tracheal development including primary branch budding and outgrowth or branch fusion.
