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).

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.
The 96 kb located at coordinates 85040-180612 of contig JSAE01000257 accurately represent the Mst77Y cluster.
Annotation CG40530 renamed CR40530 in release 5.40 of the genome annotation.
Mst77Y-16Ψ is predicted to be a pseudogene; it contains a frameshift deletion.
New annotation (CG40530) in release 5.2 of the genome annotation.
The Mst77Y region was re-evaluated using long-read single molecule sequencing technology. It was found that 6 previously identified genes (Mst77Y-2, Mst77Y-8, Mst-77Y-9, Mst77Y-5Ψ, Mst77Y-11Ψ, and Mst77y-14Ψ) were probable artifacts. Multiple new genes were identified that correspond to duplicate copies of previously identified genes. The current release 6 assembly is not entirely correct, in the order or precise sequence of the genes. The current prediction is of 10 functional copies and 8 pseudogenes in the following order, all transcribed from the plus strand: Mst77Y-17Ψ, Mst77Y-10Ψ, Mst77Y-1, Mst77Y-13, Mst77Y-3Ψ, Mst77Y-7a, Mst77Y-12a, Mst77Y-7b, Mst77Y-6aΨ, Mst77Y-6bΨ, Mst77Y-12b, Mst77Y-4a, Mst77Y-12c, Mst77Y-4b, Mst77Y-4c, Mst77Y-15Ψ, Mst77Y-16Ψ, Mst77Y-18Ψ.
"Mst77Y-16Ψ" is one of 18 Y-linked genes that are related to the Mst77F gene (which is located on 3L). Evidence suggests that these multiple copies originated from a single duplication from the autosome to the Y chromosome, followed by duplications inside the Y. Ten of these Y-linked genes encode defective proteins (Mst77Y-3Ψ, Mst77Y-5Ψ, Mst77Y-6Ψ, Mst77Y-10Ψ, Mst77Y-11Ψ, Mst77Y-14Ψ, Mst77Y-15Ψ, Mst77Y-16Ψ, Mst77Y-17Ψ and Mst77Y-18Ψ) and the other eight are potentially functional (Mst77Y-1, Mst77Y-2, Mst77Y-4, Mst77Y-7, Mst77Y-8, Mst77Y-9, Mst77Y-12 and Mst77Y-13). The eight potentially functional genes produce approximately 20% of the functional Mst77F-like mRNA and evolved under purifying selection.
CR45779 may correspond to a redundant copy of Mst77Y-16Ψ (representing the probable true location on the Y chromosome, but less complete sequence).
