Functions of the sperm surface proteins PH-20 and fertilin in arriving at, and fusing with, the egg. Biol Reprod 1997 . 56:: 320 – 327 .Myles DG , Primakoff P. Why did the sperm cross the cumulus? To get to the oocyte. Functions of the sperm surface proteins PH-20 and fertilin...
The effects on sperm functions, e.g. capacitation may be related to the specific interaction of the proteins with the phosphatidylcholin (PC) molecules in the outer leaflet of the sperm plasma membrane. The interaction of BSPA1/2 with membranes were investigated by using spin-labelled and ...
Fertilin functions in sperm-egg fusion by binding the sperm to the egg plasma membrane via a binding site in the disintegrin domain of fertilin beta. ... GR Hunnicutt,DE Koppel,DG Myles - 《Developmental Biology》 被引量: 116发表: 1997年 β1 Integrin is an Adhesion Protein for Sperm Bin...
Major sperm protein(MSP) is a 14-kDa, multifunctional, sperm-specificpolypeptidethat is essential for reproduction in nematodes. MSP polymerizes to form the filament meshworks that power sperm movement and, remarkably, also functions as an extracellular signaling molecule that promotesoocyte maturationand...
It is suggested that the sea urchin spermatozoon has on the apical part of its head a component which is complementary to the sperm-binding protein of the egg, and that the observed loss of the fertilizing capacity is caused by antedated interaction of this component with sperm-binding protein...

Genetic diversity in the Block 2 region of the merozoite surface protein 1 (MSP-1) of Plasmodium falciparum: Additional complexity and selection and conver... Fragment size in the Block 2 repetitive region of merozoite surface protein 1 (MSP1) has commonly been used as a molecular marker in ...
When sea urchin sperm is pretreated with sperm-binding protein prepared from the vitelline membrane of eggs of homologous species, it loses its fertilizing capacity entirely without losing its motility. It is not affected at all by sperm-binding protein from heterologous species. Neither agglutination...
Although they were originally described as resident proteins of the endoplasmic reticulum (ER), members of the protein disulfide isomerase (PDI) family have been reported in recent years to be on the cell surface participating in different cell functions (Turano et al., 2002). Because fusion ...
Addition of complement did not affect these results except in the antibodies to CD46 in which the reducing action was further amplified.CONCLUSIONS: Our data suggest that C1-INH, CD55, CD46, and CD59 are present on the sperm surface. These proteins may have biological functions, such as ...
