    Sperm surface proteins: Their origin, biochemical properties and role in reproduction

  • Original language description

    Seminal plasma proteins bind to the sperm surface at ejaculation and may modulate sperm properties during reproduction. Porcine spermadhesins (AQN, AWN, PSP) are secreted mainly by the seminal vesicles (SV), but their mRNAs have been found also in the cauda epididymis and prostate. Using specific polyclonal antibodies, PSP-I and PSP-II proteins were immunodetected in tissue extracts from cauda epididymis, prostate, SV and Cowper´s glands on the blots, and in secretory tissues of cauda epididymis, prostate and SV by indirect immunofluorescence. We localized PSP spermadhesins on epididymal and ejaculated spermatozoa. PSP proteins are produced not only by SV and prostate, but also by epididymis. Characterization of seminal plasma proteins expressed in theindividual reproductive organs might help to understand their role in the reproduction process.

    Povrchové proteiny spermie: původ, biochemické vlastnosti a úloha v reprodukci

  • Czech description

    Proteiny semenné plasmy se váží na povrch spermie při ejakulaci a modulují vlastnosti spermie při reprodukci. Kančí spermadhesiny (AQN, AWN, PSP) jsou sekretovány hlavně semenými vaky (SV), ale jejich mRNA byla nalezena také v cauda epididymis a prostatě. Pomocí specifických protilátek PSP I a PSP II proteiny byly imunodetekovány na blotu v tkáňových extraktech cauda epididymis, prostatě, SV, a nepřímou imunofluorescencí v sekreční tkáni cauda epididymis, prostatě, SV. Lokalizovali jsme PSP spermadhesiny na epididymálnícj a ejakulovaných spermiích. PSP proteiny jsou produkovány SV, prostatou a také nadvarletem. Charakterizace proteinů semenné plasmy exprimovaných v jednotlivých reprodukčních orgánech napomůže pochopit jejich úlohu v reprodukci
