Structural analysis of the three vitellogenin genes in Drosophila melanogaster.
Genomic fragments coding for sequences expressed as abundant mRNA in female Drosophila melanogaster were isolated from a lambda library. Hybridization of these clones to polytene chromosomes. in situ, identified four which mapped to X chromosomal region 9A to 9B, the locus for yolk proteins 1 and 2 (Ypl,2) and two which mapped to 12A6-7 to 12D3, the locus for Yp3. These clones were mapped with ...
متن کاملSequestered and Injected Vitellogenin
Vitellogenin (1, 2) is a sex-limited phosphoprotein secreted by the liver in Xenopus females (3, 4) and selectively transferred via the circulatory system to growing oocytes, within which it is converted into the yolk proteins lipovitellin and phosvitin (3, 5, 6) . Selective uptake (7) and conversion (8) of vitellogenin can also take place in isolated oocytes . The available evidence indicates ...
متن کاملVitellogenin and Vitellin in Insects
Vitellogenin is the generic name for a unique group of proteins that are synthesized extraovarially and become the major egg yolk protein, vitellin. Similar proteins are found in all animals with yolky eggs. Because of their high concentration in the egg, and the relative ease with which they can be purified, these proteins are excellent material for the study of the regulation of their synthes...
متن کاملThe Essential Role of Vitellogenin Receptor in Ovary Development and Vitellogenin Uptake in Bactrocera dorsalis (Hendel)
The vitellogenin receptor (VgR) functions as an essential component in uptaking and transporting vitellogenin (Vg) in female adults, which is involved in ovary development and oviposition. This study aimed to clarify the molecular characteristics and function of VgR in the oriental fruit fly Bactrocera dorsalis (Hendel). Here, we identified the full-length of BdVgR (GenBank Accession No. JX4691...
متن کاملVitellogenin synthesis in the avian liver. Vitellogenin is the precursor of the egg yolk phosphoproteins.
Administration of estrogen to roosters induces the synthesis of egg yolk phosphoproteins in the liver. We have demonstrated that these proteins are synthesized in the form of a large precursor, vitellogenin, and that vitellogenin is the only phosphoprotein found in the plasma of the estrogen-treated rooster. Vitellogenin is cleaved to form the egg yolk phosphoproteins, lipovitellin, and phosvit...
