Původ proteinů kančí semenné plazmy
Maňásková, Pavla ; Kyselová, Vendula ; Tichá, M. ; Jonáková, Věra
Spermadhesins were detected with their antibodies in boar epididymal fluid, but DQH and beta-microseminoprotein were not. Indirect immunofluorescence technique was employed to determine the distribution of seminal plasma proteins on tissue sections of the reproductive organs. The mRNA of the DQH was found only in seminal vesicles, not in the epididymis, and the mRNA of beta-MSP in testis, seminal vesiclas and prostate.
Vazebné vlastnosti proteinů kančí semenné plazmy v reprodukčním procesu
Jonáková, Věra ; Maňásková, Pavla ; Liberda, J. ; Tichá, M.
Boar seminal plasma proteins (spermadhesins and DQH protein)bind the sperm surface at ejaculation. binding of sperm to oviductal epithelial cells and to the glycoproteins of zona pellucida are mediated by the protein-saccharide (lectin-like)interactions.These intractions play role in the formation of sperm oviductal reservoir, in the release of capacitated sperm from the surface of oviduct and in sperm-zona pellucida interaction.
Study of aggregated forms of proteinase inhibitors from boar seminal plasma by gel chromatography
Jelínková, Petra ; Maňásková, Pavla ; Tichá, M. ; Jonáková, Věra
Most of proteins in seminal plasma exist under physiological conditions in the form of aggregates.The study of the presence of proteinase inhibitors in different associated forms of boar seminal plasma proteins is the subject of our present communicat.
Study of aggregated forms of proteinase inhibitors from boar seminl plasma by gel chromatography
Jelínková, Petra ; Maňásková, Pavla ; Tichá, M. ; Jonáková, Věra
Most of proteins in seminal plasma exist under physiological conditions in the form of aggregates. The study of the presence of proteinase inhibitosr in different associated forms of boar seminal plasma proteins is the subject of our present communication.
Proteins from boar prostate secretion: their isolation and characterization
Maňásková, Pavla ; Ryšlavá, H. ; Tichá, M. ; Jonáková, Věra
Prostate proteins were separated by affinity chromatography on immobilized heparin. Major identified components of prostate secretion:beta-microseminoprotein, serotransferin, serum albumin, PSP I and II spermadhesins.
Properties of serine proteinase inhibitors from boar seminal plasma
Jelínková, Petra ; Maňásková, Pavla ; Tichá, M. ; Jonáková, Věra
Inhibitors of proteinases are important components of seminal plasma. Their biological function in seminal plasma is to protect protein components of seminal plasma and male and female reproductive tracts against proteolytic degradation. My work is concentrated on characterization of inihibitors found in seminal plasma.
Protein interactions involved in the formation of aggregated forms of boar seminal plasma proteins
Maňásková, Pavla ; Balínová, P. ; Tichá, M. ; Jonáková, Věra
Mutual interactions of isolated proteins were tested by means of gel chromatography. The results obtained confirmed an existence of interactions between spermadhesins of the AQN and AWN families as well as between proteins involved in the formation of heterodimer PSPI/PSPII.
Serine proteinase inhibitors isolated from boar seminal plasma
Jelínková, Petra ; Maňásková, Pavla ; Tichá, M. ; Jonáková, Věra
Serine proteinase inhibitors were found in boar seminal plasma. The work was concentrated on isolation and characterization of proteinase inhibitors and study of the existence of inhibitors in complexes with other proteins in seminal plasma.
Sperm surface proteins of spermatozoa and proteins of seminal plasma in fertilization
Jonáková, Věra ; Maňásková, Pavla ; Jelínková, Petra ; Balínová, P. ; Tichá, M.
Mammalian fertilization involves highly regulated biochemical events. We aimed at study of interaction of seminal plasma proteins with sperm and at mutual interactions of proteins from seminal plasma.
