PRY (PTP-BL related on the Y chromosome) has been proposed as a candidate spermatogenesis gene. We report the characterization of the genomic structure, the number of copies on the Y chromosome and the expression of the gene. By comparison of the cDNA sequence with the genomic sequence, five exons were identified. Analysis of GenBank-derived clones on the Y chromosome revealed the presence of two full-length copies in azoospermia factor region b (AZFb) (PRY1 and PRY2) and two shorter versions of the PRY gene containing exons 3, 4 and 5 in AZFc (PRY3 and PRY4). A clone containing sequences homologous to exons 3, 4 and 5 is located in area 5L (between AZFa and AZFb), a clone containing a sequence homologous to exon 5 is located in area 5M (in AZFb) and a clone containing a fragment homologous to exon 3 is located in 6F. A repeat structure of exons 1 and 2 is present on the short arm of the Y chromosome as well as on the long arm. PRY1 and PRY2, two gene copies that are located in AZFb, a region often deleted in patients with severe male infertility, were shown to be expressed in the testis. PRY may therefore play an important role in spermatogenesis.
