Using the ligand binding domain ( LBD ) of peroxisome proliferator activated receptor ( PPARgamma ) as a model , known agonists ( thiazolidinediones and delta 12 , 14 PGJ 2 ) induced a specific interaction resulting in FRET between the fluorescently labeled LBD and fluorescently labeled coactivators [ CREB binding protein ( CBP ) or steroid receptor coactivator 1 ( SRC 1 ) ] . ^^^ A site directed AF 2 mutant of PPARgamma ( E471A ) that abrogated ligand stimulated transcription in transfected cells also failed to induce ligand mediated FRET between PPARgamma LBD and CBP or SRC 1 . ^^^ In the presence of saturating agonist concentrations , unlabeled CBP or SRC 1 was used to compete with fluorescently labeled coactivators with saturation kinetics . ^^^ Relative affinities for the individual receptor coactivator pairs were determined as follows : PPARgamma CBP = ERalpha SRC 1 > PPARgamma SRC 1 > > ERalpha CBP . ^^^ CONCLUSIONS : 1 ) FRET based coactivator association is a novel approach for characterizing nuclear receptor agonists or antagonists ; individual ligands display potencies that are predictive of in vivo effects and distinct profiles of maximal activity that are suggestive of alternative receptor conformations . 2 ) PPARgamma interacts with both CBP and SRC 1 ; transcriptional activation and coactivator association are AF 2 dependent . 3 ) Nuclear receptor LBDs have distinct affinities for individual coactivators ; thus , PPARgamma has a greater apparent affinity for CBP than for SRC 1 , whereas ERalpha interacts preferentially with SRC 1 but very weakly with CBP . . ^^^ |

Activating signal cointegrator 1 ( ASC 1 ) harbors an autonomous transactivation domain that contains a putative zinc finger motif which provides binding sites for basal transcription factors TBP and TFIIA , transcription integrators steroid receptor coactivator 1 ( SRC 1 ) and CBP p 300 , and nuclear receptors , as demonstrated by the glutathione S transferase pull down assays and the yeast two hybrid tests . ^^^ Nonetheless , ASC 1 appears to require the AF 2 dependent factors to function ( i . e . , CBP p 300 and SRC 1 ) , as suggested by the ability of ASC 1 to coactivate nuclear receptors , either alone or in cooperation with SRC 1 and p 300 , as well as its inability to coactivate a mutant receptor lacking the AF 2 core domain . ^^^ By using indirect immunofluorescence , we further show that ASC 1 , a nuclear protein , is localized to the cytoplasm under conditions of serum deprivation but is retained in the nucleus when it is serum starved in the presence of ligand or coexpressed CBP or SRC 1 . ^^^ These results suggest that ASC 1 is a novel coactivator molecule of nuclear receptors which functions in conjunction with CBP p 300 and SRC 1 and may play an important role in establishing distinct coactivator complexes under different cellular conditions . . ^^^ |
