Formation of copulatory plugs by male animals is a common means of reducing competition with rival males. In mice, copulatory plugs are formed by the coagulation of seminal vesicle secretion (SVS), which is a very viscous and self-clotting fluid containing high concentration of proteins. In its native state, mouse SVS contains a variety of disulfide-linked(More)
The molecular basis of mammalian sperm capacitation, either in vivo in the female reproductive tract, or in vitro, is poorly understood. It is well known that sperm capacitation is associated with an increase in tyrosine phosphorylation of a subset of proteins. We resolved the phosphoproteins in the cell lysate of mouse sperm after capacitation by 2-DE. One(More)
SVS I was exclusively expressed in seminal vesicle in which the protein was immunolocalized primarily to the luminal epithelium of mucosal folds. The developmental profile of its mRNA expression was shown to be androgen-dependent, manifesting a positive correlation with the animal's maturation. There are 43 glutamine and 43 lysine residues in one molecule(More)
Using mice as experimental animals, proteins in the uterine luminal fluid (ULF) from both adults and diethylstilbestrol dipropionate (DES)-treated immature animals were resolved by 2D gel electrophoresis. Two of the protein spots, (a) and (b) around the positions of 18-20 kDa, in the adult ULF were not found in the DES-treated ULF. Automated Edman(More)
