Abstract/OtherAbstract:
|
The avian vitelline membrane (VM) is a multilayered proteinaceous structure separating egg white from yolk. The innermost layer of the VM, deposited onto the oocyte plasma membrane in the ovary, corresponds to the mammalian zona pellucida (ZP). The outer layer is produced in the infundibulum, the first section of the oviduct. Using high-throughput, high-end LC-MS(n) 137 proteins were identified, only 13 of which were known previously to be components of the VM. Depending on the washing protocol, two largely overlapping, but not identical, sets of identified proteins were produced from water-washed and salt-washed VMs. Most of the components of the VM were known previously from other egg compartments, such as, for instance, the egg white proteins lysozyme C, ovalbumin, ovotransferrin, and ovomucin. Specific components of the VM not identified previously in other egg compartments included eight ZP proteins, oviductin protease, and two ATPases. The vitelline outer membrane protein (VMO) VMO II was identified as beta-defensin-11. The list of VM proteins presented in this report is by far the most comprehensive dataset available at present and complements proteomic analyses of chicken egg compartments published previously. |
