<p>Y-encoded testis-specific protein is restricted to testicular tissue (Arnemann et al., 1987; Arnemann et al., 1991; Zhang et al., 1992). Multiple TSPY sequences were shown by Manz et al. (1993) to be constitutive parts of DYZ5 repeat units. (The 'Z,' in place of 'S,' in the 'D number' indicates that it refers to repetitive DNA.) Manz et al. (1993) demonstrated microheterogeneity among transcribed and nontranscribed members of the TSPY family. Furthermore, evidence that several splice variants of TSPY transcripts occur was presented. </p><p>Schnieders et al. (1996) reported that TSPY gives rise to a pool of heterogeneously composed transcripts, at least 1 of which yields a protein that is a member of a superfamily including the protooncogene SET (600960) and NAP1 (164060), a nucleosome assembly factor. Immunohistologic studies reported by Schnieders et al. (1996) revealed that TSPY is concentrated in the cytoplasm of spermatogonia in normal as well as in pathologic tissue. They further reported that TSPY was found in the early forms of seminomatous testicular tumors. The authors suggested that TSPY function is related to spermatogonial proliferation in a phosphorylation-dependent manner. </p><p>Jakubiczka et al. (1993) isolated the bovine homolog of the human TSPY gene. The 2 proteins share 45% sequence identity. </p><p>From M. musculus testicular cDNA, Vogel et al. (1998) isolated sequences homologous to human and bovine TSPY and amplified a nearly full-length gene by PCR from mouse genomic DNA. They showed that the gene is present in single copy and apparently nonfunctional. </p>

<p>Using a combination of STS deletion mapping, binary marker and Y-short tandem repeat haplotyping, and TSPY copy number estimation, Jobling et al. (2007) identified 4 distinct classes of deletions affecting chromosome Yp in 45 males from 12 different populations. The most common deletion class was found in 41 Y chromosomes (91%) and appeared to be caused by TSPY-mediated recombination that resulted in loss of the AMELY, TBL1Y, and PRKY genes and a reduced TSPY copy number in the TSPY repeat array. The persistence and expansion of deletion lineages, together with phenotypic evidence, suggested that absence of these genes has no major deleterious effects. </p><p>Shen et al. (2013) analyzed TSPY1 copy number in 2,272 unrelated Han Chinese men, including 216 b2/b4-deleted patients with severe oligozoospermia, cryptozoospermia, or azoospermia; 326 gr/gr-deleted men with impaired spermatogenesis and 162 gr/gr-deleted controls with normozoospermia; and 870 spermatogenesis-impaired men without AZFc deletions and 698 non-AZFc-deleted controls with normozoospermia. TSPY1 copy number distributions were significantly different among non-AZFc-deleted men with different spermatogenic phenotypes; lower sperm production and an elevated risk of spermatogenic failure were observed in males with fewer than 21 TSPY1 copies and in those with more than 55 copies, compared to men with 21 to 55 copies. Similar results were observed in men with the gr/gr deletion. Shen et al. (2013) concluded that TSPY1 copy number variation (CNV) affects susceptibility to spermatogenic failure by modulating the efficiency of spermatogenesis. The authors suggested that the TSPY1 copy number has a significant quantity effect on the phenotype of the gr/gr deletion. </p>

<strong>Evolution</strong>

<span class="mim-text-font">
<p>Guttenbach et al. (1992) demonstrated conservation of DYZ5-homologous sequences on the Y chromosome of primates. </p><p>TSPY genes must have been selectively maintained on the mammalian Y chromosome since before the radiation of eutheria, 80 million years ago, as they are found conserved on the Y chromosome in 2 mammalian orders: primate and artiodactyl. Mazeyrat and Mitchell (1998) identified TSPY on the mouse and rat Y chromosome. The gene structure and expression of rat TSPY suggested that it is a functional, testis-specific gene, but the closely related mouse gene, Tspy, has clearly become nonfunctional, producing only low levels of aberrantly spliced transcripts. Thus, TSPY lost its function in the mouse lineage after its divergence from the rat lineage. These observations appeared to support the impression that recombination prevents genetic deterioration in sexual populations because it allows conservation of functional genotypes by removing deleterious mutations. The absence of recombination may have led to the loss of a functional Tspy gene in the mouse. </p>

To ensure long-term funding for the OMIM project, we have diversified
our revenue stream. We are determined to keep this website freely
accessible. Unfortunately, it is not free to produce. Expert curators
review the literature and organize it to facilitate your work. Over 90%
of the OMIM's operating expenses go to salary support for MD and PhD
science writers and biocurators. Please join your colleagues by making a
donation now and again in the future. Donations are an important
component of our efforts to ensure long-term funding to provide you the
information that you need at your fingertips.
