摘要


Spermadhesins belong to a novel family of secretory proteins of the male genital tract. They are major proteins of the seminal plasma and have been found peripherally associated to the sperm surface. So far, they have only been detected in ungulates, specifically in pig, cattle, and horse, respectively. Spermadhesins form a subgroup of the superfamily of proteins with a CUB-domain that has been found in a variety of developmentally regulated proteins. The structure and function of the spermadhesins have been investigated in the pig. They are multifunctional proteins showing a range of ligand-binding abilities, e.g. to carbohydrates, phospholipids, and protease inhibitors, suggesting that they may be involved in different steps of fertilization. We report here the genomic organization of the porcine spermadhesin gene cluster as well as a detailed comparative analysis with respect to other mammalian species. The porcine spermadhesin genes are located on SSC 14q28-q29 in a region syntenic to HSA 10q26. The pig contains five closely linked spermadhesin genes, whereas only two spermadhesin genes are present in the cattle genome. Inactive copies of spermadhesin genes are still detectable in the human, chimp, and dog genome while the corresponding region was lost from the rodent genomes of mouse and rat. Within the pig, the five spermadhesin genes contain both highly diverged and highly conserved regions. Interestingly, the pattern of divergence does not correlate with the position of the exons. Evolutionary analyses suggest that the pattern of diversity is shaped by ancestral variation, recombination, and new mutations.
