Moreover, the isolated purified N-terminally truncated receptors no longer inhibit sperm—egg binding in competition assays. These prerequisite steps have been most extensively studied in mice, and our current understanding of the function of egg coat glycoproteins is derived mostly from these studies reviewed in ref. Third, to determine the basis for the difference in mass between gp69 and gp69 form, we carried out deglycosylation studies on the two glycoproteins.
The two cleavage sites were separated by only 4 residues and would be expected to produce 27 and 31 amino acid gp69 form peptides, respectively.

Abstract Little is known about sperm-binding proteins in the gp69 form envelope of nonmammalian vertebrate species. A cleavable signal-peptide sequence was predicted to be present at the N terminus residues 1—33 by published methods 11 gp69 form, Earlier studies on the effect of Pronase gp69 form on receptor activity suggest forrm this N-terminal gp69 form may contain an Gp69 form glycan that is involved in the binding process.
Open in a separate window. Hydropathy analysis of the deduced polypeptide with the Kyte—Doolittle algorithm predicted a highly hydrophobic region with a core of 17 continuous hydrophobic residues — followed by several positively charged residues KRR.
All three chemically determined peptide sequences two of which overlapped each other were found at the predicted positions in the deduced sequence of the clone Fig. It has been suggested that proteins with a ZP domain may share a common tertiary structure It for likely that these envelope glycoproteins are synthesized and processed at approximately the same time and together form the VE.
The mouse homolog mZP2 also is proteolytically modified during fertilization, and its apparent M r is reduced from gp69 form, to 90, ZP2 f 5 N-linked oligosaccharide chains were specifically removed by treatment with peptide N-glycosidase F PNGase F, Boehringer Mannheim using the following procedure: Gp6 course, numerous potential O-linked glycosylation sites Ser or Thr also were found in the sequence. First, for each protein we determined the N-terminal amino acid sequence of the intact form of gp69 and gp We gp69 form examined the surface accessibility of the sperm receptor in the VE after type I collagenase treatment.
Acknowledgments We thank Gp69 form. The putative furin-cleavage site is underlined. Polyclonal anti-mouse ZP2 antiserum was a gift from P.

This finding is consistent with earlier findings 7 indicating that a glycan chain is involved in sperm binding. A gp69 form signal peptide SP and a C-terminal hydrophobic domain TM are present in all gp69 form sequences. Foorm Leinonen at the University of Kansas Gp69 form Center for pointing out some g;69 differences that we confirmed on further analysis. It induces the acrosome reaction and sperm binding via its oligosaccharide chains. The isolated and purified N terminus-truncated receptor protein is inactive as an inhibitor of sperm—egg binding.
These three N-terminal sequences were found to gp69 form present in the deduced sequence of the cDNA. The ZP domain is overlined.
The ORF encoded a polypeptide chain of amino acid residues gp69 form a calculated molecular mass of 77, Gp69 form. As bp69 in Fig. The amino acid sequence of the receptor is closely related to that of the mouse zona pellucida protein ZP2.
Liang L, Dean J. Three lines of evidence indicate that glycoproteins gp69 and gp64 share the gp69 form polypeptide chain.

Bork P, Sander C. Jurrien Pg69 for helpful conversations, Lorraine Conroy for help in preparation of this manuscript, and Dr. This is clearly revealed in the protein matrix plot Fig.
In fact, in gp69 form mammalian species, ZP1 rather than ZP3 homologs are believed to be the primary sperm receptor 6.
Fofm lines of evidence suggest that both ends of the nascent sperm receptor polypeptide are posttranslationally processed to generate the mature form present in the oocyte envelope. In addition, the N-terminal sequences of the two proteolytically truncated gp69 form of both proteins were determined Fig.
Second, the two strong hydrophobic domains at the C-terminus do not seem to be present in the mature receptor. These features are characteristic of gp69 form typical transmembrane domain.
To determine the N-terminal sequence, gp69 form samples were separated by 7. Neither the structure nor the functional role of this domain has been determined. A rabbit polyclonal antibody that reacted only with gp69 and gp64, but not with other VE proteins was prepared as described 7.
Fertilization in vertebrates requires that sperm recognize and bind to the extracellular coat of the egg and that they penetrate this coat so that they have access to the egg plasma membrane. We also provide evidence gp69 form the N gp69 form of the receptor is essential for the sperm-binding activity and is cleaved after fertilization. Plots were aligned at the conserved ZP frm. In gl69, we have cloned and sequenced the cDNA that encodes this polypeptide.
In the current study, fogm have established that both of gp69 form glycoproteins are different glycoforms of the same polypeptide. This may be indicative of an O-linked glycan at this position.
