COUP-TFII (COUP transcription factor 2), also known as NR2F2 (nuclear receptor subfamily 2, group F, member 2) is a protein that in humans is encoded by the NR2F2 gene. [5] [6] The COUP acronym stands for chicken ovalbumin upstream promoter.
COUP-TFII plays a critical role in controlling the development of a number of tissues and organs including heart, blood vessels, muscles and limbs. [7] [8]
The glucocorticoid receptor (GR) stimulates COUP-TFII-induced transactivation while COUP-TFII represses the GR transcriptional activity. [9] [10] COUP-TFII interacts with GATA2 to inhibit adipocyte differentiation. [11]
The structure of COUP-TF2 LBD is known. Retinoic acid, although not at physiological concentrations, activate this receptor. [12]
COUP-TFII has been shown to interact with:
Histone acetyltransferase p300 also known as p300 HAT or E1A-associated protein p300 also known as EP300 or p300 is an enzyme that, in humans, is encoded by the EP300 gene. It functions as histone acetyltransferase that regulates transcription of genes via chromatin remodeling by allowing histone proteins to wrap DNA less tightly. This enzyme plays an essential role in regulating cell growth and division, prompting cells to mature and assume specialized functions (differentiate), and preventing the growth of cancerous tumors. The p300 protein appears to be critical for normal development before and after birth.
Estrogen receptor alpha (ERα), also known as NR3A1, is one of two main types of estrogen receptor, a nuclear receptor that is activated by the sex hormone estrogen. In humans, ERα is encoded by the gene ESR1.
The nuclear receptor coactivator 2 also known as NCoA-2 is a protein that in humans is encoded by the NCOA2 gene. NCoA-2 is also frequently called glucocorticoid receptor-interacting protein 1 (GRIP1), steroid receptor coactivator-2 (SRC-2), or transcriptional mediators/intermediary factor 2 (TIF2).
The chicken ovalbumin upstream promoter transcription factor (COUP-TFs) proteins are members of the nuclear receptor family of intracellular transcription factors. There are two variants of the COUP-TFs, labeled as COUP-TFI and COUP-TFII encoded by the NR2F1 and NR2F2 genes respectively.
V-erbA-related protein 2 (EAR-2) also known as NR2F6 is a protein that in humans is encoded by the NR2F6 gene. V-erbA-related protein 2 is a member of the nuclear receptor family of intracellular transcription factors. It is named after its similarity to v-erbA, a helper of an oncoprotein called v-erbB in avian erythroblastosis virus.
Retinoid X receptor alpha (RXR-alpha), also known as NR2B1 is a nuclear receptor that in humans is encoded by the RXRA gene.
Nuclear receptor-interacting protein 1 (NRIP1) also known as receptor-interacting protein 140 (RIP140) is a protein that in humans is encoded by the NRIP1 gene.
Serum response factor, also known as SRF, is a transcription factor protein.
COUP-TF1 also known as NR2F1 is a protein that in humans is encoded by the NR2F1 gene. This protein is a member of nuclear hormone receptor family of steroid hormone receptors.
Mediator of RNA polymerase II transcription subunit 1 also known as DRIP205 or Trap220 is a subunit of the Mediator complex and is a protein that in humans is encoded by the MED1 gene. MED1 functions as a nuclear receptor coactivator.
General transcription factor II-I is a protein that in humans is encoded by the GTF2I gene.
E3 SUMO-protein ligase PIAS2 is an enzyme that in humans is encoded by the PIAS2 gene.
Mediator of RNA polymerase II transcription subunit 14 is an enzyme that in humans is encoded by the MED14 gene.
Tripartite motif-containing 24 (TRIM24) also known as transcriptional intermediary factor 1α (TIF1α) is a protein that, in humans, is encoded by the TRIM24 gene.
General transcription factor II-I repeat domain-containing protein 1 is a protein that in humans is encoded by the GTF2IRD1 gene.
Mediator of RNA polymerase II transcription subunit 21 is an enzyme that in humans is encoded by the MED21 gene.
B-cell lymphoma/leukemia 11B is a protein that in humans is encoded by the BCL11B gene.
Peroxisome proliferator-activated receptor gamma coactivator-related protein 1 is a protein that in humans is encoded by the PPRC1 gene.
Endothelial differentiation-related factor 1 is a protein that in humans is encoded by the EDF1 gene.
Nuclear receptor coregulators are a class of transcription coregulators that have been shown to be involved in any aspect of signaling by any member of the nuclear receptor superfamily. A comprehensive database of coregulators for nuclear receptors and other transcription factors was previously maintained at the Nuclear Receptor Signaling Atlas website which has since been replaced by the Signaling Pathways Project website.
