  • Scalarin carries and stabilizesĀ carotenoidĀ pigments

    ScalarinĀ (PsSC) is the most abundantĀ perivitellinĀ of theĀ perivitelline fluidĀ fromĀ Pomacea scalarisĀ eggs. This glyco-lipo-caroteno protein is an approx. 380 kDa multimer combining multiple copies of six different 24-35 kDa subunits. As part of theĀ petivitelline fluid, PsSC is probably playing a role as a nutrient source for the developing embryo inĀ Pomacea scalarisĀ eggs. As its orthologousĀ ovorubinĀ andĀ PmPV1, this protein carries and stabilizesĀ carotenoidĀ pigments.Ā As…

  • Pomacea maculataĀ perivitellin-1Ā (PmPV1) is a glyco-lipo-caroteno protein

    Pomacea maculataĀ perivitellin-1Ā (PmPV1) is the most abundantĀ perivitellinĀ found in theĀ perivitelline fluidĀ fromĀ Pomacea maculataĀ snail eggs. This glyco-lipo-caroteno protein is an approx. 294 kDa multimer of a combination of multiple copies of six different ~30 kDa subunits.Ā Ā PmPV1 account >60% of the totalĀ proteinsĀ found in theĀ Pomacea maculataĀ eggs.Ā  PmPV1 is an orthologous ofĀ ovorubinĀ andĀ scalarin, sharing most of the structural features with the former protein…

  • Ovorubin

    OvorubinĀ (PcOvoĀ orĀ PcPV1) is the most abundantĀ perivitellinĀ (>60Ā % totalĀ protein) of theĀ perivitelline fluidĀ fromĀ Pomacea canaliculataĀ snail eggs. This glyco-lipo-caroteno protein complex is a approx. 300 kDa multimer of a combination of multiple copies of six different ~30 kDa subunits. Together with the otherĀ perivitellinsĀ fromĀ Pomacea canaliculataĀ eggs, ovorubin serves a nutrient source for developing embryos, notably to the intermediate and late stages.Ā Moreover, after hatching,…
