SF conflict in protein sequence between EMBL entries #U14533 (443 aa) and #U20389 (446 aa): insertion of 3 aa at pos. 53 and substitution at pos. 33 (G versus V);
SF subcellular location predominantly nuclear [3];
SF long N-terminal domain (77aa) domain mainly consisting of PEST sequence, which is apparently characteristic for proteins with short half-lives [2];
SF ligand-binding domain (LBD) not highly homologous to other members of the nuclear receptor family [3];
SF contains a 5 aa P-Box which is supposed to be responsible for hormone response element (HRE) half-site recognition in other nuclear receptors [2] [1] [3];
SF a heptad-repeat leucin zipper structure in the C-terminal ligand binding domain is suspected to be important for heterodimerization [3];
SF heterodimerization with RXR-alpha T04383 even in the absence of DNA and formation of a complex with transactivation capability [2];
SF forms homodimers (which bind to R09956 but with poor transcriptional transactivation activity) [3];

CP ubiquitous expression in fetal and adult tissues [2] [3]; (fetal:) (in situ) high levels in thymus, brown fat tissue, spleen gastrointestinal tract, salivary gland, thyroid gland, pituitary gland, retina and moderate levels in liver lung heart, skin [2]; (adult:) high levels in liver, ovary, heart, testis, vagina, uterus, kidney, adrenal, spleen [3] and brain (cerebellum and hippocampus [2]) and in situ in lymph node and prostate [2] [2] [3].

FF enhances transcriptional transactivation activity of RXR-alpha T04383 most likely by forming heterodimers: this increase is higher upon exposure to natural ligand (9-cis retinoid acid) but occurs even in its absence [2];
FF evidence for modulation of gene activation in retinoic acid and thyroid hormone signaling pathways in an inhibitory manner: presence of factor apparently decreases transcriptional transactivation activity of heterodimer RXR-alpha/RAR-alpha1 and homodimer of RXR-alpha T01345 at binding site R09956 [3];
