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: data from FlyAtlas
As part of a survey of ciliary motility gene homologs in Drosophila, expression of kl-5 was assayed in motile ciliated cell types. Expression was observed in sperm (testis) but not chordotonal neurons.

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.

Identification: PCR screen for Dynein heavy chain genes.
kl-5 has been cloned and characterised.
kl-5 gene locus encodes a dynein heavy chain, the dynein heavy chain sequences are localised to the kl-5 region of the Y chromosome. These results provide evidence that at least one of the Y chromosome fertility regions encodes a polypeptide required for spermatogenesis.
AAGAC satellite DNA repeats which map to the kl-5 and ks-1 loop forming regions are abundantly transcribed in primary spermatocytes. These transcripts are detected at all stages of development of these two loops, do not appear to migrate to the cytoplasm and are degraded when the loops disintegrate during the first meiotic prophase.
Males mutant for kl-5 fail to assemble the outer dynein arms associated with the A tubules of the peripheral doublets of the sperm tail axoneme (Hardy, Tokuyasu, and Lindsley, 1981). Such males also fail to produce kl-5-specific 300-325 kilodalton sperm polypeptide considered to be a component of the outer arms (Goldstein, Hardy and Lindsley, 1982). kl-5 mutants exhibit very low level of fertility at 25oC but not at 18oC and in young but not older males (Kennison, 1983). Deficiencies for kl-5 completely sterile and in addition to the mutant phenotype they fail to produce aggregates of tubuli normally seen in thin sections of primary spermatocyte nuclei (Hardy et al., 1981). Within the kl-5 fertility region of the spermatocyte nucleus, a loop-forming site has been demonstrated by its reaction with the monoclonal antibody S5 (Bonaccorsi et al., 1988). These loops are stained with the protein-specific dye CBB, but are not visible in living preparations.
