The zona pellucida (ZP) is an extracellular glycoprotein coat that is deposited around the oocyte during folliculogenesis and performs several functions that relate to fertilisation and preimplantion development. In eutherian mammals it consists of three major glycoproteins--ZPA, ZPB, and ZPC--but little is known about its molecular constitution in marsupials. We have isolated the cDNA encoding the ZPA homologue in two distantly related marsupial series: the possum, Trichosurus vulpecula (a… CONTINUE READING
