Journal ArticleDOI
Spermadhesins: A new protein family. Facts, hypotheses and perspectives
Edda Töpfer-Petersen,Antonio Romero,Paloma F. Varela,M. Ekhlasi-Hundrieser,Z. Dostàlovà,Libia Sanz,Juan J. Calvete +6 more
TL;DR: Spermadhesins are a novel family of secretory proteins expressed in the male genital tract of pig, horse and bull and have been found to be peripherally associated to the sperm surface, suggesting that they may be involved in different steps of fertilization.
Journal ArticleDOI
The crystal structures of two spermadhesins reveal the CUB domain fold
Antonio Romero,Maria João Romão,Paloma F. Varela,Ingo Kölln,João M. Dias,Ana Luísa Carvalho,Libia Sanz,Edda Töpfer-Petersen,Juan J. Calvete +8 more
TL;DR: The authors reported the crystal structures of porcine seminal plasma PSP-I/PSP-II, a heterodimer of two glycosylated spermadhesins, and bovine aSFP at 2.4 A and 1.9 A resolution respectively.
Journal ArticleDOI
Selective sperm binding to pig oviductal epithelium in vitro.
TL;DR: Individual differences revealed by this study and their relation to morphology and contact of spermatozoa with seminal fluid indicate a selective function of sperm-oviduct binding.
Journal ArticleDOI
Isolation and characterization of heparin‐ and phosphorylcholine‐binding proteins of boar and stallion seminal plasma. Primary structure of porcine pB1
TL;DR: The characterization of heparin‐ and phosphorylcholine‐binding proteins of stallion and boar seminal plasma tie in with the hypothesis that homologous proteins from different mammalian species may display distinct biological activities, which may be related to species‐specific aspects of sperm physiology.
Journal ArticleDOI
The role of stallion seminal proteins in fertilisation.
TL;DR: The major proteins of equine seminal plasma have been isolated and characterised regarding their expression along the male genital tract, protein structure and their functions.
