Nuclear hormone receptors in nematodes: evolution and function.
Nuclear hormone receptors (NHRs) are proteins that regulate gene expression in response to developmental, environmental, and nutritional signals. The activity of some NHRs is selectively and reversibly modulated by small molecular weight compounds. However, for others - termed "orphan" receptors - no such ligands have (yet) been identified, and at least some NHRs may lack natural ligands. NHRs ...
متن کاملNuclear hormone receptors and gene expression.
The nuclear hormone receptor superfamily includes receptors for thyroid and steroid hormones, retinoids and vitamin D, as well as different "orphan" receptors of unknown ligand. Ligands for some of these receptors have been recently identified, showing that products of lipid metabolism such as fatty acids, prostaglandins, or cholesterol derivatives can regulate gene expression by binding to nuc...
متن کاملGene repression by nuclear hormone receptors.
Repression by nuclear hormone receptors (NHRs) plays an important role in development, immune response and cellular function. We review mechanisms of how NHRs act as repressors of gene transcription either by direct contact with basal transcription factors or through recruitment of cofactors and enzymic activities that modulate chromatin accessibility. We describe also the role and biochemical ...
متن کاملNUREBASE: database of nuclear hormone receptors
Nuclear hormone receptors are an abundant class of ligand activated transcriptional regulators, found in varying numbers in all animals. Based on our experience of managing the official nomenclature of nuclear receptors, we have developed NUREBASE, a database containing protein and DNA sequences, reviewed protein alignments and phylogenies, taxonomy and annotations for all nuclear receptors. Th...
متن کاملNuclear Hormone Receptors in T Lymphocytes
Among the numerous steroid and orphan nuclear receptors encoded within mammalian genomes, several are involved in regulating immune system functions. We review here recent studies on the glucocorticoid receptor and the orphan receptors Nur77 and RORgamma. These molecules play key roles in the development and the effector functions of T lymphocytes.
