title: Mouse seminal vesicle secretory protein of 99 amino acids (MSVSP99): characterization and hormonal and developmental regulation.
abstract: Polyclonal antibodies have been generated to investigate the localization, tissue and species distribution, androgen regulation, and ontogeny of a protein secreted by mouse seminal vesicle, designated as MSVSP99 (ie, mouse seminal vesicle secretory protein of 99 amino acids). MSVSP99 is a polymorphic compound with a molecular weight of around 14 kilodaltons and a positive immunoreactivity range of 5.23 to 5.70. Positive immunoreactivity was restricted to the epithelial cells of the seminal vesicle. Western blot analysis showed organ specificity for MSVSP99, which could not be detected in several organs in the mouse. Time course decrease of MSVSP99 after castration closely followed that of its mRNA. In contrast, the length of time required to restore control levels after testosterone treatment was higher for the protein than it was for its mRNA. Whereas the MSVSP99 gene is already active in 10-day-old males, MSVSP99 is first detected at 27 days. Then, we conclude that factors other than the accumulation of the mRNA regulate MSVSP99 expression.
