Functions of Vitellogenin in Eggs.
Results and problems in cell differentiation, 2017Our understanding of the functions of vitellogenin (Vtg) in reproduction has undergone an evolutionary transformation over the past decade. Primarily, Vtg was regarded as a female-specific reproductive protein, which is cleaved into yolk proteins including phosvitin (Pv) and lipovitellin (Lv), stored in eggs, providing the nutrients for early embryos ...

Molecular characteristics of insect vitellogenins and vitellogenin receptors
Insect Biochemistry and Molecular Biology, 1998The recent cloning and sequencing of several insect vitellogenins (Vg), the major yolk protein precursor of most oviparous animals, and the mosquito Vg receptor (VgR) has brought the study of insect vitellogenesis to a new plane. Insect Vgs are homologous to nematode and vertebrate Vgs.

Determination of locust vitellogenin by radioimmunoassay with [3H]propionyl-vitellogenin
General and Comparative Endocrinology, 1983A simple procedure for radiolabeling of locust vitellogenin is described. This procedure involves coupling of [3H]propionyl succinimidate to purified vitellogenin with high yield and specific activity. Using this radiolabeled analog, a specific and sensitive radioimmunoassay was developed for determining locust vitellogenin content, with a lower ...

Abstract Polysomes from estrogenized rooster liver were subfractionated on sucrose gradients. The size distribution of the vitellogenin polysomes was determined with in vitro labelling of the nascent chains followed by immunochemical determination of the elongated vitellogenin chains. Vitellogenin polysomes contain 30–40 ribosomes.

Bacterial endosymbionts play essential roles in the biology of their arthropod hosts by interacting with internal factors in the host. The whitefly Bemisia tabaci is a worldwide agricultural pest and a supervector for more than 100 plant viruses.

Molecular characteristics of insect vitellogenins
Journal of Insect Physiology, 2008Vitellogenins (Vgs) are precursors of the major egg storage protein, vitellin (Vn), in many oviparous animals. Insects Vgs are large molecules ( approximately 200-kD) synthesized in the fat body in a process that involves substantial structural modifications (e.g., glycosylation, lipidation, phosphorylation, and proteolytic cleavage, etc.) of the ...

Evolutionary Conservation of Vitellogenin Genes
DNA, 1982Homologous and heterologous hybridizations in solution were performed between sheared genomic DNA and DNA complementary to vitellogenin mRNA of Xenopus, chicken, and migratory locust. The kinetics of hybridization and the thermal stability of the hybrids formed suggested a high degree of conservation of coding sequences of insect, amphibian, and avian ...

The insect yolk precursor vitellogenin is a lipoglycoprotein synthesized and stored in the fat body and secreted into the hemolymph. In honey bees, vitellogenin displays crucial functions in hormone signaling, behavioral transition of nurse bees to ...

Bactericera cockerelli vitellogenin‐6 like, a vitellogenin without a direct reproductive function?
Insect Molecular Biology, 2017Abstract Vitellogenin‐like proteins are members of the large lipid transfer proteins, a family of proteins involved in reproduction, lipid circulation and immune defences. In this study, we identified a new Bactericera cockerelli vitellogenin‐like (Vg‐like) transcript, and ...

Gene, 2000
By analysis of zebrafish EST (expressed sequence tag) clones from an adult cDNA library, we have identified 44 clones, about 11% of the adult EST clones, encoding vitellogenins. These vitellogenin EST clones have been derived from at least seven distinct vitellogenin genes.
