The Porcine TSPY Gene Is Tricopy but Not a Copy Number Variant.

ABSTRACT: The testis-specific protein Y-encoded (TSPY) gene is situated on the mammalian Y-chromosome and exhibits some remarkable biological characteristics. It has the highest known copy number (CN) of all protein coding genes in the human and bovine genomes (up to 74 and 200, respectively) and also shows high individual variability. Although the biological function of TSPY has not yet been elucidated, its specific expression in the testis and several identified binding domains within the protein suggests roles in male reproduction. Here we describe the porcine TSPY, as a multicopy gene with three copies located on the short arm of the Y-chromosome with no variation at three exon loci among 20 animals of normal reproductive health from four breeds of domestic pigs (Piétrain, Landrace, Duroc and Yo
