PROTEIN

PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	one modulating N terminal domain
	both 'zinc-fingers' of the DNA-binding domain are encoded separately in two exons and the ligand-binding domain is assembled from five exons
	C terminal steroid binding domain

HOMOLOGY

interspecies

homolog to murine Rarb

Homologene

FAMILY

nuclear hormone receptor family

CATEGORY

DNA associated , transcription factor , tumor suppressor , receptor nuclear

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm
	intracellular,nucleus,nucleoplasm
	intracellular,nucleus,chromatin/chromosome

basic FUNCTION	morphogen controlling cell functions by directly regulating gene expression
	possible role of the retinol pathway in the development of lipodystrophy phenotypes
	frequently deleted or epigenetically silenced at early stages in tumor progression and corresponds to a tumor suppressor
	its activity is essential for proper differentiation of ES cells to pancreatic endocrine cells
	crucial role of the retinoic acid pathway during eye development and organogenesis

Type Gene Modification Chromosome rearrangement Protein expression Protein Function constitutional     --low   by hypermethylation in patients with familial partial lipodystrophy and LMNA gene mutations (R482L and R471G) tumoral     --low   by promoter region methylation is an early event in endometrial carcinogenesis tumoral   deletion     or weakly expressed in esophageal cancer by hypermethylation of the promoter tumoral     --low   by hypermethylation in non-small cell lung cancer (NSCLC) more frequent in females compared to males

Susceptibility

to meningomyelocele (MM)

Variant & Polymorphism SNP	rs6799734, rs12630816, rs17016462 conferred a protective effect for MM susceptibility

Candidate gene	detection of methylation of the gene in blood might have utility in monitoring and detecting tumor recurrence in early-stage non-small cell lung cancer after curative surgical resection
Marker
Therapy target	AM580 (a RAR-specific agonist might be considered as a potential treatment for endometrial carcinoma
	potential pharmacological target to the regulation of stem cell function (chondrogenesis can be induced using a synthetic inhibitor of the retinoic acid receptor)
