Glucocorticoid receptor (GR) is a ligand-dependent nuclear receptor which regulates the transcription of a wide spectrum of genes that are responsible for vital immunological, metabolic, developmental, and anti-inflammatory functions. GR transcriptional regulatory effects are modulated by co-regulators including the tetratricopeptide 5 (TTC5) which has been shown to stabilize GR and alter its action in response to cellular stress. TTC5 is a stress-responsive activator of p300 ...

Glucocorticoid receptor (GR) is a hormone-dependent nuclear transcription factor that modulates the expression of genes involved in development, inflammation, and metabolism. In addition, as GR is a key factor in several steroid dependent cancers steroid hormones are extensively used in the treatment of cancers such as leukemia. The transcriptional activity of GR is cell type specific and its magnitude and target selectivity depend on multiple factors including posttranslation...

Cofactors of the nuclear hormone receptors are crucial in regulating their transcriptional activity. The glucocorticoid receptor (GR) is a member of the nuclear hormone receptor superfamily, involved in the regulation of metabolism, inflammation and stress–responses and many GR cofactors are known, including p300. Here, we identify a new cofactor for GR: TTC5/Strap, tetratricopeptide repeat domain 5/ stress–responsive activator of p300. Strap is a TPR motif containin...
