Abstract

BACKGROUND:

In 2002 Takamatsu and co-workers described the human DSCR9 gene and observed that it was transcriptionally active in human testicular tissue, but no protein was identified as a product of this transcript. Similar results were obtained in chimpanzee tissue. This gene has not been detected in species other than primates, suggesting that DSCR9 is exclusively found in these mammals.

RESULTS:

We report evidence of DSCR9 expression in placenta, testis and kidney of baboon (Papio hamadryas). We used primers specific for DSCR9 to amplify transcripts through reverse transcription (RT) coupled to polymerase chain reaction (PCR). Furthermore, PCR was used to amplify the complete DSCR9 gene from genomic DNA from three baboons. We amplified and sequenced five overlapping segments that were assembled into the 3284 bp baboon DSCR9 gene, including the putative promoter and the entire transcriptional unit (5'-UTR, CDS and 3'-UTR).

CONCLUSIONS:

The baboon DSCR9 gene is highly similar to the human counterpart. The isolated transcripts from baboon tissues (placenta, testis and kidney) of three different baboons correspond to the human orthologous gene.
