The Retinoblastoma Binding Protein RBP2 Is an H3K4 Demethylase
Changes in histone methylation status regulate chromatin structure and DNA-dependent processes such as transcription. Recent studies indicate that, analogous to other histone modifications, histone methylation is reversible. Retinoblastoma binding protein 2 (RBP2), a nuclear protein implicated in the regulation of transcription and differentiation by the retinoblastoma tumor suppressor protein,...
متن کاملHigh Expression of Retinoblastoma-Binding Protein 2 (RBP2) in Patients with Hepatocellular Carcinoma and Its Prognostic Significance
BACKGROUND Recently, some studies have found that retinoblastoma-binding protein 2 (RBP2) is involved in the development and progression of many kinds of malignant tumors. This study aimed to explore the expression level of RBP2 in hepatocellular carcinoma (HCC) and its prognostic significance. MATERIAL AND METHODS Immunohistochemical analysis was used to evaluate the RBP2 expression level in 1...
متن کاملLoss of the retinoblastoma binding protein 2 (RBP2) histone demethylase suppresses tumorigenesis in mice lacking Rb1 or Men1.
Aberrations in epigenetic processes, such as histone methylation, can cause cancer. Retinoblastoma binding protein 2 (RBP2; also called JARID1A or KDM5A) can demethylate tri- and dimethylated lysine 4 in histone H3, which are epigenetic marks for transcriptionally active chromatin, whereas the multiple endocrine neoplasia type 1 (MEN1) tumor suppressor promotes H3K4 methylation. Previous studie...
متن کاملThe role of thyroid hormone receptor DNA binding in negative thyroid hormone-mediated gene transcription.
Thyroid hormone 3,3',5-tri-iodothyronine (T3) regulates gene expression in a positive and negative manner. Here, we analyzed the regulation of a positively (mitochondrial glycerol-3-phosphate dehydrogenase) and negatively T3-regulated target gene (TSHalpha). Thyroid hormone receptor (TR) activates mGPDH but not TSH promoter fragments in a mammalian one-hybrid assay. Furthermore, we investigated...
متن کاملRetinoblastoma protein is functionally distinct from its homologues in affecting glucocorticoid receptor-mediated transcription and apoptosis.
The cell cycle regulator, retinoblastoma protein, is known to potentiate glucocorticoid receptor-activated transcription through the interaction of its pocket domain with the transcription coactivator, hBRM. We now show that glucocorticoid receptor-induced apoptosis is also dependent on both the retinoblastoma protein and hBRM. p107 and p130, which share extensive sequence homology with the poc...
