Structure and organization of the mouse acrosin gene.
The genomic region carrying the mouse acrosin gene, including the 5'-flanking sequence, has been isolated and characterized. The acrosin gene consists of five exons separated by four introns. Organization of this gene is very similar to those of the genes for other typical serine proteases, except for the phase class of the first intron. Riboprobe mapping and primer extension analyses showed that the start site of transcription initiation in the acrosin gene is heterogeneous, including three major sites. Thus, the structure and organization of the mouse acrosin gene are different from those of the human gene [Keime, S., Adham, I.M., & Engel, W. (1990) Eur. J. Biochem. 190, 195-200] in two respects: the number of transcription initiation sites and the phase class of the third intron. The putative promoter regions of the mouse and human acrosin genes lack typical sequences of TATA, CAAT, and GC boxes, but contain a consensus sequence, GGGTGGG, known to be specific for the phosphoglycerate kinase-2 gene, and the protamine-1 and 2 genes that are uniquely expressed during spermatogenesis.
