核受体 (Nuclear Receptors)

Estrogen Receptor is a major ligand-activated transcription factor belonging to the nuclear hormone receptor superfamily. Estrogen Receptor is composed of several domains important for hormone binding, DNA binding, and activation of transcription. The protein localizes to the nucleus where it may form a homodimer or a heterodimer with estrogen receptor 2. Estrogen and its receptors are essential for sexual development and reproductive function, but they also play a role in other tissues such as bone. Estrogen receptors are also involved in pathological processes including breast cancer, endometrial cancer, and osteoporosis. Alternative splicing results in several transcript variants, which differ in their 5' UTRs and use different promoters.

Thyroid hormone receptor beta (THRB), also known as TRbeta and NR1A2, belongs to the nuclear hormone receptor family. Featuring an N-terminal transactivation domain, a central DNA-binding domain, and a hormone ligand-binding domain, THRB isoform 1 2 expression localizes predominately to the liver and pituitary, respectively. THRB regulates the feedback of T3-dependent thyrotropin-stimulating hormone (TSH) transcription in the pituitary by binding to thyroid hormone (TH) response elements present on promoters of TH-responsive genes. Located on chromosome 3p24, THRB gene mutation has been linked to autosomal dominant resistance to TH (RTH), which is characterized by goiter and elevated levels of T3, T4, and TSH. THRB is a known pharmacological target for the treatment of non-alcoholic steatohepatitis (NASH). THRB may be a target for future cancer therapies since its knockdown enhanced the viability of endometrial cancer cells and activated the mTOR-4EBP1 eIF4G pathway.

Nuclear hormone receptor. Binds estrogens with an affinity similar to that of ESR1 ER-alpha, and activates expression of reporter genes containing estrogen response elements (ERE) in an estrogen-dependent manner.; Lacks ligand binding ability and has no or only very low ERE binding activity resulting in the loss of ligand-dependent transactivation ability.

Transcriptional regulator which is important for the differentiation and maintenance of meso-diencephalic dopaminergic (mdDA) neurons during development. It is crucial for expression of a set of genes such as SLC6A3, SLC18A2, TH and DRD2 which are essential for development of mdDA neurons.

Peroxisome proliferator-activated receptor gamma (PPARG), a nuclear hormone receptor, plays a critical role in the lipid and glucose homeostasis, adipocyte differentiation, as well as intracellular insulin-signaling events. The peroxisome proliferator-activated receptor gamma (PPARgamma) regulates osteoblast and osteoclast differentiation, and is the molecular target of thiazolidinediones (TZDs), insulin sensitizers that enhance glucose utilization and adipocyte differentiation. Peroxisome proliferator-activated receptor gamma (PPARG) is a transcription factor involved in atherosclerosis and related diseases. Peroxisome proliferator-activated receptor gamma (PPARG) plays an important role in the pathogenesis and maintenance of essential hypertension (EH).The functional single nucleotide polymorphisms in peroxisome proliferator-activated receptor gamma (PPARG) gene were predicted to be correlated with the susceptibility of colorectal cancer (CRC).

Receptor that binds peroxisome proliferators such as hypolipidemic drugs and fatty acids.

May play a role in the regulation of circadian rhythm.
