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).

al protein is expressed in both male and female genital discs of third instar larvae. Expression is more extensive and at a higher level in female than in male discs.

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.
In the leg, al is only required for the growth and differentiation of the tip of the leg and not for the formation of the proximo-distal axis.
Genetic combinations with mutants of nub cause additive phenotypes.
al gene has been cloned, identified and characterised.
"al" mutant phenotype resembles that reported for "tg" mutants. Since "tg" is genetically closely linked to "al" it may be allelic to "al".
