This domain represents a conserved region found in several lipid transport proteins including vitellogenin microsomal triglyceride transfer protein and apolipoprotein B-100.Vitellogenin precursors provide the major egg yolk proteins that are a source of nutrients during early development of oviparous vertebrates and invertebrates. Vitellinogen precursors are multi-domain apolipoproteins that are cleaved into distinct yolk proteins.
