Lac Repressors. Lac Repressor . LacI Proteins . Proteins, LacI . Repressor, Lac . Repressors, Lac . Bacterial repressor proteins that bind to the LAC OPERON and thereby prevent the synthesis of proteins involved in catabolism of LACTOSE. When lactose levels are high lac repressors undergo an allosteric change that causes their release from the DNA and the resumption of lac operon transcription. . 1.00
Repressor Proteins. Transcriptional Silencing Factors . Proteins, Repressor . Silencing Factors, Transcriptional . Repressor Molecules . Proteins which maintain the transcriptional quiescence of specific GENES or OPERONS. Classical repressor proteins are DNA-binding proteins that are normally bound to the OPERATOR REGION of an operon, or the ENHANCER SEQUENCES of a gene until a signal occurs that causes their release. . 0.60

Co Repressor Proteins . Co Repressors . Co-Repressors, Nuclear Receptor . Corepressors, Nuclear Receptor . Nuclear Hormone Receptor Co Repressors . Nuclear Receptor Co Repressors . Receptor Co-Repressors, Nuclear . A subclass of repressor proteins that do not directly bind DNA. Instead, co-repressors generally act via their interaction with DNA-BINDING PROTEINS such as a TRANSCRIPTIONAL SILENCING FACTORS or NUCLEAR RECEPTORS. . 0.57
