title: The gene for the major protein (SVSP109) of bovine semen: structure and promoter analysis.
abstract: We have characterized the gene of SVSP109, specifying the bovine secretory protein SVSP109, which is synthesized in a tissue- as well as species-specific manner. Approximately 1.3 kb upstream of the SVSP109 gene, the 3'-end of another gene designated HG5 was identified. The HG5 gene fragment comprises exon (n-1) and exon (n), separated by an intron. Exon (n) contains the complete 3'-untranslated region, whereas exon (n-1) encodes the C-terminal part of a hitherto unknown protein with high homology to SVSP109. The sequenced region of 6956 bp of a bovine genomic clone comprised the complete SVSP109 gene, which is made up of five exons and four introns. Primer extension analysis and RTPCR of poly(A+)RNA from seminal vesicle revealed that the first exon 1 extends to a position 34 bp downstream of the TATA sequence. Employing a CAT assay, a definitive but weak promoter activity was detected in pCATeSVSP15 (base pairs -639 to +574) and pCATeSVSP10 (base pairs -639 to +198); pCATeSVSP6 (base pairs -262 to +65) displayed promoter activity similar to the positive control. We conclude from these results that the TATA sequence located at position -34 is part of the functional promoter of the SVSP109 gene.
