Partial purification of a progesterone-inducible messenger RNA (avidin) from hen oviduct.

Journal Article

The messenger RNA (mRNA) for avidin, which represents less than 0.05% of the total cellular proteins, was partially purified from hen oviduct, and the presence of avidin mRNA was shown to depend upon prior stimulation by progesterone. A total nucleic acid extract was subjected to oligo (dT)-cellulose chromatography, followed by Sepharose 4B chromatography, preparative agarose gel electrophoresis, and sucrose gradient centrifugation. The relative purity of each preparation was assessed by translation in a wheat-germ system; avidin messenger RNA activity was measured by specific immunoprecipitation of synthesized proteins. Avidin mRNA was separated from the bulk of the total messenger RNA activity of the oviduct and from all ribosomal RNAs to produce greater than a 1000-fold enrichment of avidin mRNA activity compared with total cellular RNA. Based on the translation assay, the most highly purified fraction contained about 2.5% avidin messenger RNA. Avidin mRNA activity was absent in partially purified mRNA obtained from estrogen-stimulated chick oviducts, but was detected in oviducts following progesterone administration.
