Abstract |
Pituitary adenylate cyclase-activating polypeptide (PACAP) is a pleiotropic neuropeptide localized in the testis at concentration comparable to that found in the brain, suggesting involvement in spermatogenesis. In this study, we identified the human PACAP testis-specific exon (TSE) 10.9 kb upstream from the translational start site and found that the testis-specific transcript of the human PACAP gene was found to be spliced from the TSE into a region of intron 2 without a frameshift. The resulting PACAP precursor has no signal peptide, suggesting that PACAP functions physiologically in an intracrine manner in the testis. The 5'-flanking region of the TSE contains an 80-bp fragment with potent promoter activity in testicular F9 cell. Electrophoresis mobility shift assays showed that proteins from the F9 nuclear extract interacted specifically with the 80-bp fragment. DNA affinity chromatography allowed isolation of the specific proteins bound to the 80-bp fragment, two of which were identified as Poly (ADP-ribose) polymerase-1 (PARP-1) and TIA-1-related protein (TIAR) by mass spectrometry. By using their siRNAs, the depletion of their proteins in F9 cells affected the potent promoter activity of the 80-bp fragment, suggesting that they might be involved in the testis-specific gene expression of PACAP.
