Negative feedback control of jasmonate signaling by an alternative splice variant of JAZ10 [PDF]
, 2013 The plant hormone jasmonate (JA) activates gene expression by promoting ubiquitin-dependent degradation of JAZ transcriptional repressor proteins. A key feature of all JAZ proteins is the highly conserved Jas motif, which mediates both JAZ degradation ...

Structure, 1996 Crystal and cocrystal structures of the LacI and PurR repressors reveal a novel use of hinge alpha helices which bind in the minor groove of the operator and mediate transmission of the allosteric signals that modulate DNA-binding activity.

Crystallization and preliminary crystallographic analysis of dUTPase from the helper phage Φ11 of Staphylococcus aureus [PDF]
, 2011 Staphylococcus aureus superantigen-carrying pathogenicity islands (SaPIs) have a determinant role in spreading virulence genes among bacterial populations that constitute a major health hazard.

Allelic expression mapping across cellular lineages to establish impact of non‐coding SNPs
Molecular Systems Biology, 2014 Most complex disease‐associated genetic variants are located in non‐coding regions and are therefore thought to be regulatory in nature. Association mapping of differential allelic expression (AE) is a powerful method to identify SNPs with direct cis ...

The GbsR Family of Transcriptional Regulators: Functional Characterization of the OpuAR Repressor
Frontiers in Microbiology, 2018 Accumulation of compatible solutes is a common stress response of microorganisms challenged by high osmolarity; it can be achieved either through synthesis or import.

Conversion of graded to binary response in an activator-repressor system [PDF]
Phys. Rev. E 81, 021905 (2010), 2009 Appropriate regulation of gene expression is essential to ensure that protein synthesis occurs in a selective manner. The control of transcription is the most dominant type of regulation mediated by a complex of molecules such as transcription factors. In general, regulatory molecules are of two types: activator and repressor.
