Vitellogenin — A Biomarker for Endocrine Disruptors

TrAC Trends in Analytical Chemistry, 1998
The increasing preponderance of females in fish populations has become a matter of concern not only for scientists but also for environmental authorities. For example, in the extensive waterways in Berlin, Germany, 70% of the fish population is female.

Vitellogenesis and the Vitellogenin Gene Family

Science, 1981
Vitellogenin is synthesized under estrogen control in the liver, extensively modified, transported to the ovary, and there processed to the yolk proteins lipovitellin and phosvitin. In the frog Xenopus laevis there are at least four distinct but related vitellogenin genes.

Vitellogenin protein diversity in the HawaiianDrosophila

Biochemical Genetics, 1990
Egg and female hemolymph proteins were resolved via SDS-polyacrylamide gel electrophoresis in a diverse array of 33 endemic Hawaiian drosophilids, encompassing 17 picture-winged species, 3 of the antopocerus species group, 9 fungus feeders, 1 species from each of the modified mouthparts, crassifemur and ciliated tarsus groups, and 1 Scaptomyza species.

Evolution and expression of vitellogenin genes

Trends in Genetics, 1988
Abstract A major event during the growth period of oocytes in nonmammalian animals is the accumulation of yolk. The genes coding for the yolk protein precursor, known as vitallogenin, are well characterized in a few vertebrate and invertebrate species.

Problem‐solving test: Vitellogenin and vitellogenin‐receptor recognition: An example of protein interaction

Biochemistry and Molecular Biology Education, 2011
AbstractTerms and concepts to understand before starting to solve the test questions: Yeast two‐hybrid screening system, glutathione S‐transferase (GST)1 pull‐down assay, bait protein, prey protein, site‐directed mutagenesis, restriction enzymes, protein‐protein interaction, β‐galactosidase reporter assay, and amino acid properties.

Study of Vitellogenin Motif

Vitellogenin (VTG) is known to be a female-specific protein and a precursor form of egg yolk.Threevitellogenin,Vtg I,Vtg II and Vtg III have been identified in chicken.Vitellinogen precursors supply themajor egg yolk proteins which are a source of nutrients during early development of egg-laying(oviparous) vertebrates and invertebrates.
