Nuclear hormone receptor family, NR1 subfamily

Nuclear hormone receptor

Retinoic acid receptors bind as heterodimers to their target response elements in response to their ligands, all-trans or 9-cis retinoic acid, and regulate gene expression in various biological processes. The RXR/RAR heterodimers bind to the retinoic acid response elements (RARE) composed of tandem 5'-AGGTCA-3' sites known as DR1-DR5. In the absence of ligand, the RXR-RAR heterodimers associate with a multiprotein complex containing transcription corepressors that induce histone acetylation, chromatin condensation and transcriptional suppression. On ligand binding, the corepressors dissociate from the receptors and associate with the coactivators leading to transcriptional activation. RARA plays an essential role in the regulation of retinoic acid-induced germ cell development during spermatogenesis. Has a role in the survival of early spermatocytes at the beginning prophase of meiosis. In Sertoli cells, may promote the survival and development of early meiotic prophase spermatocytes. In concert with RARG, required for skeletal growth, matrix homeostasis and growth plate function. Receptor for retinoic acid.

Chromosomal aberrations involving RARA are commonly found in acute promyelocytic leukemia. Translocation t(11;17)(q32;q21) with ZBTB16/PLZF; translocation t(15;17)(q21;q21) with PML; translocation t(5;17)(q32;q11) with NPM. The PML-RARA oncoprotein requires both the PML ring structure and coiled-coil domain for both interaction with UBE2I, nuclear microspeckle location and sumoylation. In addition, the coiled-coil domain functions in blocking RA-mediated transactivation and cell differentiation. {ECO:0000269|PubMed:12691149, ECO:0000269|PubMed:8302850, ECO:0000269|PubMed:8562957}.

Substrate recognition component of a DCX (DDB1-CUL4-X-box) E3 protein ligase complex that mediates the ubiquitination and subsequent proteasomal degradation of target proteins, such as MEIS2. Normal degradation of key regulatory proteins is required for normal limb outgrowth and expression of the fibroblast growth factor FGF8. May play a role in memory and learning by regulating the assembly and neuronal surface expression of large-conductance calcium-activated potassium channels in brain regions involved in memory and learning via its interaction with KCNT1. Binding of pomalidomide and other thalidomide-related drugs changes the substrate specificity of the human protein, leading to decreased degradation of MEIS2 and other target proteins and increased degradation of MYC, IRF4, IKZF1 and IKZF3.

Anemia, non-spherocytic hemolytic, due to G6PD deficiency (NSHA) [MIM:300908]: A disease characterized by G6PD deficiency, acute hemolytic anemia, fatigue, back pain, and jaundice. In most patients, the disease is triggered by an exogenous agent, such as some drugs, food, or infection. Increased unconjugated bilirubin, lactate dehydrogenase, and reticulocytosis are markers of the disorder. Although G6PD deficiency can be life-threatening, most patients are asymptomatic throughout their life. {ECO:0000269|PubMed:12524354, ECO:0000269|PubMed:1303180, ECO:0000269|PubMed:1303182, ECO:0000269|PubMed:1536798, ECO:0000269|PubMed:1611091, ECO:0000269|PubMed:1889820, ECO:0000269|PubMed:1945893, ECO:0000269|PubMed:20007901, ECO:0000269|PubMed:26479991, ECO:0000269|PubMed:2836867, ECO:0000269|PubMed:2912069, ECO:0000269|PubMed:30988594, ECO:0000269|PubMed:38066190, ECO:0000269|PubMed:7858267, ECO:0000269|PubMed:7959695, ECO:0000269|PubMed:8193373, ECO:0000269|PubMed:8490627, ECO:0000269|PubMed:8533762, ECO:0000269|PubMed:8733135, ECO:0000269|PubMed:9452072}. The disease is caused by variants affecting the gene represented in this entry. Deficiency of G6PD is associated with hemolytic anemia in two different situations. First, in areas in which malaria has been endemic, G6PD-deficiency alleles have reached high frequencies (1% to 50%) and deficient individuals, though essentially asymptomatic in the steady state, have a high risk of acute hemolytic attacks. Secondly, sporadic cases of G6PD deficiency occur at a very low frequencies, and they usually present a more severe phenotype. Several types of NSHA are recognized. Class-I variants are associated with severe NSHA; class-II have an activity <10% of normal; class-III have an activity of 10% to 60% of normal; class-IV have near normal activity.

Immunoglobulin

As a ligand for the inhibitory receptor PDCD1/PD-1, modulates the activation threshold of T-cells and limits T-cell effector response. Through a yet unknown activating receptor, may costimulate T-cell subsets that predominantly produce interleukin-10 (IL10). Plays a critical role in induction and maintenance of immune tolerance to self.

Truncation of the 3'-untranslated (3'-UTR) region of CD274 transcripts leads to elevated expression of CD274 in multiple cancers including T-cell leukemia, diffuse large B-cell lymphoma and stomach adenocarcinoma (PubMed:27281199). Disruption of 3'-UTR region is caused by structural variants that stabilize CD274 transcripts, leading to overexpression (PubMed:27281199). Increased expression in tumors promotes immune evasion and tumor cell growth by allowing malignant cells to escape destruction by the immune system (PubMed:27281199). {ECO:0000269|PubMed:27281199}.

Acyltransferase

Acetylates all four core histones in nucleosomes. Histone acetylation gives an epigenetic tag for transcriptional activation. Mediates cAMP-gene regulation by binding specifically to phosphorylated CREB protein. Mediates acetylation of histone H3 at 'Lys-122' (H3K122ac), a modification that localizes at the surface of the histone octamer and stimulates transcription, possibly by promoting nucleosome instability. Mediates acetylation of histone H3 at 'Lys-27' (H3K27ac). Also functions as acetyltransferase for non-histone targets, such as ALX1, HDAC1, PRMT1 or SIRT2. Acetylates 'Lys-131' of ALX1 and acts as its coactivator. Acetylates SIRT2 and is proposed to indirectly increase the transcriptional activity of TP53 through acetylation and subsequent attenuation of SIRT2 deacetylase function. Acetylates HDAC1 leading to its inactivation and modulation of transcription. Acts as a TFAP2A-mediated transcriptional coactivator in presence of CITED2. Plays a role as a coactivator of NEUROD1-dependent transcription of the secretin and p21 genes and controls terminal differentiation of cells in the intestinal epithelium. Promotes cardiac myocyte enlargement. Can also mediate transcriptional repression. Acetylates FOXO1 and enhances its transcriptional activity. Acetylates BCL6 wich disrupts its ability to recruit histone deacetylases and hinders its transcriptional repressor activity. Participates in CLOCK or NPAS2-regulated rhythmic gene transcription; exhibits a circadian association with CLOCK or NPAS2, correlating with increase in PER1/2 mRNA and histone H3 acetylation on the PER1/2 promoter. Acetylates MTA1 at 'Lys-626' which is essential for its transcriptional coactivator activity. Acetylates XBP1 isoform 2; acetylation increases protein stability of XBP1 isoform 2 and enhances its transcriptional activity. Acetylates PCNA; acetylation promotes removal of chromatin-bound PCNA and its degradation during nucleotide excision repair (NER). Acetylates MEF2D. Acetylates and stabilizes ZBTB7B protein by antagonizing ubiquitin conjugation and degragation, this mechanism may be involved in CD4/CD8 lineage differentiation. In addition to protein acetyltransferase, can use different acyl-CoA substrates, such as (2E)-butenoyl-CoA (crotonyl-CoA), butanoyl-CoA (butyryl-CoA) or propanoyl-CoA (propionyl-CoA), and is able to mediate protein crotonylation, butyrylation or propionylation, respectively. Acts as a histone crotonyltransferase; crotonylation marks active promoters and enhancers and confers resistance to transcriptional repressors. Histone crotonyltransferase activity is dependent on the concentration of (2E)-butenoyl-CoA (crotonyl-CoA) substrate and such activity is weak when (E)-but-2-enoyl-CoA (crotonyl-CoA) concentration is low. Also acts as a histone butyryltransferase; butyrylation marks active promoters. Functions as a transcriptional coactivator for SMAD4 in the TGF-beta signaling pathway. Acetylates PCK1 and promotes PCK1 anaplerotic activity. Functions as histone acetyltransferase and regulates transcription via chromatin remodeling.

Homo sapiens (Human)

Ubiquitin-specific-processing protease 2; Ubiquitin thioesterase 2; UBP41; Deubiquitinating enzyme 2; 41 kDa ubiquitin-specific protease

Peptidase C19 family, USP2 subfamily

Peptidase

Isoform 1 and isoform 4 possess both ubiquitin-specific peptidase and isopeptidase activities. Deubiquitinates MDM2 without reversing MDM2-mediated p53/TP53 ubiquitination and thus indirectly promotes p53/TP53 degradation and limits p53 activity. Has no deubiquitinase activity against p53/TP53. Prevents MDM2-mediated degradation of MDM4. Plays a role in the G1/S cell-cycle progression in normal and cancer cells. Regulates the circadian clock by modulating its intrinsic circadian rhythm and its capacity to respond to external cues. Associates with clock proteins and deubiquitinates core clock component PER1 but does not affect its overall stability. Regulates the nucleocytoplasmic shuttling and nuclear retention of PER1 and its repressive role on the clock transcription factors CLOCK and ARNTL/BMAL1. Plays a role in the regulation of myogenic differentiation of embryonic muscle cells. Hydrolase that deubiquitinates polyubiquitinated target proteins such as MDM2, MDM4 and CCND1.
