Interaction with retinoic acid receptor (RXR) shifts RXR from its role as a silent DNA-binding partner to an active ligand-binding subunit in mediating retinoid responses through target genes defined by LXRES. LXRES are DR4-type response elements characterized by direct repeats of two similar hexanuclotide half-sites spaced by four nucleotides. Plays an important role in the regulation of cholesterol homeostasis, regulating cholesterol uptake through MYLIP-dependent ubiquitination of LDLR, VLDLR and LRP8. Interplays functionally with RORA for the regulation of genes involved in liver metabolism. Nuclear receptor that exhibits a ligand-dependent transcriptional activation activity.

Ovarian tumorassociated antigen MOv18; KB cells FBP; Folate receptor, adult; Folate receptor 1; FRalpha; FOLR1; Adult folatebinding protein

Folate receptor family

Folate receptor

Binds to folate and reduced folic acid derivatives and mediates delivery of 5-methyltetrahydrofolate and folate analogs into the interior of cells. Has high affinity for folate and folic acid analogs at neutral pH. Exposure to slightly acidic pHafter receptor endocytosis triggers a conformation change that strongly reduces its affinity for folates and mediates their release. Required for normal embryonic development and normal cell proliferation.

Neurodegeneration due to cerebral folate transport deficiency (NCFTD) [MIM:613068]: An autosomal recessive neurodegenerative disorder resulting from brain-specific folate deficiency early in life. Onset is apparent in late infancy with severe developmental regression, movement disturbances, epilepsy and leukodystrophy. {ECO:0000269|PubMed:19732866}.

RARA

Homo sapiens (Human)

RAR-alpha; RAR alpha; Nuclear receptor subfamily 1 group B member 1; NR1B1

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}.

Diabetic retinopathy remains the major cause of new-onset blindness among diabetic adults. It is characterized by vascular permeability and increased tissue ischemia and angiogenesis. Disease susceptibility is associated with variants affecting the gene represented in this entry. Homozygosity for the Leu-55 allele is strongly associated with the development of retinal disease in diabetic patients.

Cerebral creatine deficiency syndrome 2 (CCDS2) [MIM:612736]: An autosomal recessive disorder characterized by developmental delay and regression, intellectual disability, severe disturbance of expressive and cognitive speech, intractable seizures, movement disturbances, severe depletion of creatine and phosphocreatine in the brain, and accumulation of guanidinoacetic acid in brain and body fluids. {ECO:0000269|PubMed:12468279, ECO:0000269|PubMed:15108290, ECO:0000269|PubMed:15651030, ECO:0000269|PubMed:16293431, ECO:0000269|PubMed:16855203, ECO:0000269|PubMed:17101918, ECO:0000269|PubMed:17466557, ECO:0000269|PubMed:19388150, ECO:0000269|PubMed:23660394, ECO:0000269|PubMed:24415674, ECO:0000269|PubMed:8651275}.

CHRNA2

Homo sapiens (Human)

CHRNA2

Ligand-gated ion channel (TC 1.A.9) family, Acetylcholine receptor (TC 1.A.9.1) subfamily, Alpha-2/CHRNA2 sub-subfamily

Neurotransmitter receptor

After binding acetylcholine, the AChR responds by an extensive change in conformation that affects all subunits and leads to opening of an ion-conducting channel across the plasma membrane.

Epilepsy, nocturnal frontal lobe, 4 (ENFL4) [MIM:610353]: An autosomal dominant focal epilepsy characterized by nocturnal seizures associated with fear sensation, tongue movements, and nocturnal wandering, closely resembling nightmares and sleep walking. {ECO:0000269|PubMed:16826524}. The disease is caused by variants affecting the gene represented in this entry.; DISEASE: Seizures, benign familial infantile, 6 (BFIS6) [MIM:610353]: A form of benign familial infantile epilepsy, a neurologic disorder characterized by afebrile seizures occurring in clusters during the first year of life, without neurologic sequelae. BFIS6 inheritance is autosomal dominant. {ECO:0000269|PubMed:25847220}. The disease may be caused by variants affecting the gene represented in this entry.

HCN2

Homo sapiens (Human)

Potassium/sodium hyperpolarization-activated cyclic nucleotide-gated channel 2; Brain cyclic nucleotide-gated channel 2; BCNG2; BCNG-2

Potassium channel HCN family

Voltage-gated ion channel

Contributes to the native pacemaker currents in heart (If) and in neurons (Ih). Can also transport ammonium in the distal nephron. Produces a large instantaneous current. Modulated by intracellular chloride ions and pH; acidic pH shifts the activation to more negative voltages. Hyperpolarization-activated ion channel exhibiting weak selectivity for potassium over sodium ions.

Epilepsy, idiopathic generalized 17 (EIG17) [MIM:602477]: A form of idiopathic generalized epilepsy, a disorder characterized by recurring generalized seizures in the absence of detectable brain lesions and/or metabolic abnormalities. Generalized seizures arise diffusely and simultaneously from both hemispheres of the brain. Seizure types include juvenile myoclonic seizures, absence seizures, and generalized tonic-clonic seizures. Both autosomal dominant and autosomal recessive EIG17 inheritance have been reported. {ECO:0000269|PubMed:22131395, ECO:0000269|PubMed:29064616}. Disease susceptibility is associated with variants affecting the gene represented in this entry.; DISEASE: Febrile seizures, familial, 2 (FEB2) [MIM:602477]: Seizures associated with febrile episodes in childhood without any evidence of intracranial infection or defined pathologic or traumatic cause. It is a common condition, affecting 2-5% of children aged 3 months to 5 years. The majority are simple febrile seizures (generally defined as generalized onset, single seizures with a duration of less than 30 minutes). Complex febrile seizures are characterized by focal onset, duration greater than 30 minutes, and/or more than one seizure in a 24 hour period. The likelihood of developing epilepsy following simple febrile seizures is low. Complex febrile seizures are associated with a moderately increased incidence of epilepsy. FEB2 transmission pattern is consistent with autosomal dominant inheritance. {ECO:0000269|PubMed:24324597}. The disease is caused by variants affecting the gene represented in this entry.
