Sperm surface proteins after capacitation. Expression of vitronectin on the spermatozoan head and laminin on the sperm tail
Sperm surface proteins vitronectin spermatozoan head laminin sperm tail
2009/2/11
Several integrins recognize as ligands proteins containing the Arg-Gly-Asp (RGD) sequence, such as fibronectin, vitronectin, and laminin. It has been previously demonstrated that oligopeptides con...
Sperm surface fibronectin. Expression following capacitation
Sperm surface fibronectin Expression capacitation
2009/2/10
The Arg-Gly-Asp (RGD) amino acid sequence plays a role in many cell-to-cell and cell-to-matrix adhesion systems, as a recognition sequence for cell membrane receptors termed integrins. Receptors of ...
Use of neonatal tolerization and chemical immunosuppression for the production of monoclonal antibodies to maturation-specific sperm surface molecules
neonatal tolerization chemical immunosuppression monoclonal antibodies
2009/2/7
Mammalian sperm acquire functional maturity as they move from the caput to the cauda epididymidis. Changes occur in the protein/glycoprotein composition of the sperm plasma membrane during this time...
Importance of glycosylation and disulfide bonds in hyaluronidase activity of macaque sperm surface PH-20
Enzyme activity glycoprotein protein structure deglycosylation
2008/12/30
PH-20 is a glycoprotein located on the surface of the sperm plasma membrane and on the inner acrosomal membrane. The best understood function of sperm surface PH-20 is its hyaluronidase activity, ...
Cryopreservation alters the levels of the bull sperm surface protein P25b
Cryopreservation bull sperm surface protein P25b
2008/12/25
Fertility of frozen-thawed bull sperm is reduced by cryopreservation. Freezing-thawing procedures can result in as much as a sevenfold fertility decrease. Sperm mortality and loss of motility do not...
Limited Processing of Pro-Matrix Metalloprotease-2（Gelatinase A）Overexpressed by Transfection in PC-3 Human Prostate Tumor Cells: Association With Restricted Cell Surface Localization of Membrane-Type Matrix Metalloproteinase-1
Tissue inhibitor of metalloproteinase-2 prostate cancer Concanavalin A reverse transcriptase-polymerase chain reaction
2008/12/22
The expression and activation of matrix metalloproteinases (MMPs) by tumor cells is correlated with progression to invasive and metastatic status. The purpose of this study was to examine the role of ...
Binding of Protein D/E to the Surface of Rat Epididymal Sperm Before Ejaculation and After Deposition in the Female Reproductive Tract
Epididymal secretory protein interaction sperm plasma membrane
2008/12/5
The objectives of the present investigation were to study the interaction of protein D/E with the surface of rat epididymal spermatozoa and to assess its topology on the spermatozoa surface before a...
