yolk proteins การใช้

• These are used as building blocks for the synthesis of egg yolk proteins.
• Vitellinogen precursors are multi-domain apolipoproteins that are cleaved into distinct yolk proteins.
• Vitellogenin precursors provide the major egg yolk proteins that are a source of nutrients during early development of oviparous vertebrates and invertebrates.
• Different vitellinogen precursors exist, which are composed of variable combinations of yolk protein components; however, the cleavage sites are conserved.
• DSX-F causes transcription of Yolk proteins 1 and 2 in somatic cells, which will be pumped into the oocyte on its production.
• In insects ( as in other non-mammalian animals ), egg maturation begins with vitellogenesis, the deposition of yolk proteins triggered by the release of juvenile hormones.
• In vertebrates, a complete vitellinogen is composed of an N-terminal signal peptide for export, followed by four regions that can be cleaved into yolk proteins : lipovitellin-1, phosvitin, lipovitellin-2, and a von Willebrand factor type D domain ( YGP40 ).
