Comments
Comment typeDescription
FunctionBinds to an ERR-alpha response element (ERRE) containing a single consensus half-site, 5'-TNAAGGTCA-3'. Can bind to the medium-chain acyl coenzyme A dehydrogenase (MCAD) response element NRRE-1 and may act as an important regulator of MCAD promoter. Binds to the C1 region of the lactoferrin gene promoter. Requires dimerization and the coactivator, PGC-1A, for full activity. The ERRalpha/PGC1alpha complex is a regulator of energy metabolism. Induces the expression of PERM1 in the skeletal muscle.
PtmPhosphorylation on Ser-19 enhances sumoylation on Lys-14 increasing repression of transcriptional activity
PtmReversibly acetylated. Acetylation by PCAF/KAT2 at Lys-129, Lys-138, Lys-160 and Lys-162 and PCAF/KAT2 decreases transcriptional activity probably by inhibiting DNA-binding activity; deacetylation involves SIRT1 and HDAC8 and increases DNA-binding (By similarity)
PtmSumoylated with SUMO2. Main site is Lys-14 which is enhanced by phosphorylation on Ser-19, cofactor activation, and by interaction with PIAS4. Sumoylation enhances repression of transcriptional activity, but has no effect on subcellular location nor on DNA binding (By similarity)
Sequence CautionSequence=AAI04702.1; Type=Erroneous initiation; Evidence= ; Sequence=AAQ17212.1; Type=Frameshift; Positions=408, 413; Evidence= ;
SimilarityBelongs to the nuclear hormone receptor family. NR3 subfamily
SimilarityContains 1 nuclear receptor DNA-binding domain
Subcellular LocationNucleus {ECO:0000255|PROSITE- ProRule:PRU00407}.
SubunitBinds DNA as a monomer or a homodimer. Interacts (via the AF2 domain) with coactivator PPARGC1A (via the L3 motif); the interaction greatly enhances transriptional activity of genes involved in energy metabolism. Interacts with PIAS4; the interaction enhances sumoylation (By similarity)
