Analysis of Rice Proteins with DLN Repressor Motif/S [PDF]
International Journal of Molecular Sciences, 2019 Transcriptional regulation includes both activation and repression of downstream genes. In plants, a well-established class of repressors are proteins with an ERF-associated amphiphilic repression/EAR domain. They contain either DLNxxP or LxLxL as the identifying hexapeptide motif. In rice (Oryza sativa), we have identified a total of 266 DLN repressor

The transcriptional repressor protein NsrR senses nitric oxide directly via a [2Fe-2S] cluster [PDF]
, 2008 The regulatory protein NsrR, a member of the Rrf2 family of transcription repressors, is specifically dedicated to sensing nitric oxide (NO) in a variety of pathogenic and non-pathogenic bacteria.

Heterotropic regulation and negative homotropic cooperativity. [PDF]
FEBS Open BioWe identified a structural module common to some proteins that couple negative cooperativity with heterotropic regulation, two features that rarely coexist. These proteins are ring‐like and present an ordered asymmetry whereby noncontacting subunits are symmetric, and their tertiary structure differs from that of contacting subunits.

Kaiso is a genome-wide repressor of transcription that is essential for amphibian development [PDF]
, 2004 DNA methylation in animals is thought to repress transcription via methyl-CpG specific binding proteins, which recruit enzymatic machinery promoting the formation of inactive chromatin at targeted loci.

Repressor of Phage 16-3 with Altered Binding Specificity Indicates Spatial Differences in Repressor-Operator Complexes [PDF]
, 2006 The C repressor protein of phage 16-3, which is required for establishing and maintaining lysogeny, recognizes structurally different operators which differ by 2 bp in the length of the spacer between the conserved palindromic sequences.

BiFCROS: A Low-Background Fluorescence Repressor Operator System for Labeling of Genomic Loci
G3: Genes, Genomes, Genetics, 2017 Fluorescence-based methods are widely used to analyze elementary cell processes such as DNA replication or chromosomal folding and segregation. Labeling DNA with a fluorescent protein allows the visualization of its temporal and spatial organization. One

Closely related proteins MBD2 and MBD3 play distinctive but interacting roles in mouse development [PDF]
, 2001 MBD2 and MBD3 are closely related proteins with consensus methyl-CpG binding domains. MBD2 is a transcriptional repressor that specifically binds to methylated DNA and is a component of the MeCP1 protein complex.

A dominant repressor version of the tomatoSl-ERF.B3gene confers ethylene hypersensitivity via feedback regulation of ethylene signaling and response components [PDF]
, 2013 Ethylene Response Factors (ERFs) are downstream components of the ethylene signal transduction pathway, although their role in ethylene-dependent developmental processes remains poorly understood. As the ethylene-inducible tomato Sl-ERF.B3 has been shown

KPNB1 mediates PER/CRY nuclear translocation and circadian clock function
eLife, 2015 Regulated nuclear translocation of the PER/CRY repressor complex is critical for negative feedback regulation of the circadian clock of mammals. However, the precise molecular mechanism is not fully understood.
