Repressors of photomorphogenesis

2002
The internal programs of plant development are informed in a profound way by environmental light conditions. This review summarizes the contribution of repressor proteins to the light-signaling machinery during seedling development, and discusses the integration of repressors with other, positively acting, light-signaling pathways and auxin and ...

Lac Repressor

Angewandte Chemie International Edition in English, 1971
AbstractRepressors are proteins that interact with inducers and operators to regulate the synthesis of enzymes in the cell. Lac repressor ensures that sufficient β‐galactosidase is available to the bacterium Escherichia coli, depending upon the amount of lactose present in the culture medium. It has proved possible to isolate lac repressor from E.coli.

Toti“potent” repressors

BioEssays, 2006
AbstractA fascinating property of germ cells is their ability to maintain totipotency throughout development. At fertilization, this totipotency is unleashed and the egg generates all the cell types needed to make a brand new organism. Occasionally, germ cells differentiate precociously in the embryo or in the gonads and form teratomas, tumors ...

A mechanism for repressor action

Journal of Molecular Biology, 1969
Abstract Deletion mutants have been isolated in which the three structural genes of the lac operon, z , y and a , and the lac operator are fused to the trp operon. In most of these strains, the rate of lac operon expression is greatly increased by the derepression of the trp operon.

Translational repressors in Drosophila

Trends in Genetics, 2002
Translational regulation is an important aspect of gene regulation, particularly during early development of the fruit fly embryo when transcriptional mechanisms are untenable. Study of pattern formation and dosage compensation has identified several repressors that bind discrete sites in the untranslated portions of target mRNAs.

Studies of a thermolabile repressor

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1965
Abstract From physiological and genetic evidence, it is concluded that the repressor for β-galactosidase (EC 3.2.1.23) synthesis in a mutant bacterium, E-103, is thermolabile. The apparent inactivation of repressor is first order and irreversible; however, paradoxically, only a characteristic fraction can be inactivated at a given temperature ...

Co‐repressors 2000

The FASEB Journal, 2000
ABSTRACT In the last 5 years, many co‐repressors have been identified in eukaryotes that function in a wide range of species, from yeast to Drosophila and humans. Co‐repressors are coregulators that are recruited by DNA‐bound transcriptional silencers and play essential ...
