RA Tucker M.A., Polk D.H.;
RT "Cloning of the alpha and beta ovine thyroid hormone receptor cDNAs.";
RL Thyroid 6:237-243(1996).
CC -!- FUNCTION: Nuclear hormone receptor that can act as a repressor or
CC activator of transcription. High affinity receptor for thyroid
CC hormones, including triiodothyronine and thyroxine.
CC -!- SUBUNIT: Binds DNA as a dimer; homodimer and heterodimer with RXRB.
CC Interacts with NCOA3 and NCOA6 coactivators, leading to a strong
CC increase of transcription of target genes. Probably interacts with
CC SFPQ. Interacts with C1D. Interacts with AKAP13. Interacts with
CC TP53INP2. Interacts with PER2 (By similarity). Interacts with TACC1.
CC The interaction with isoform alpha-1, but not alpha-2, is decreased in
CC the presence of thyroid hormone T3 (By similarity). {ECO:0000250,
CC ECO:0000250|UniProtKB:P10827}.
CC -!- SUBCELLULAR LOCATION: Nucleus.
CC -!- SUBCELLULAR LOCATION: [Isoform Alpha-2]: Cytoplasm
CC {ECO:0000250|UniProtKB:P63058}. Nucleus {ECO:0000250|UniProtKB:P63058}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=Alpha-1;
CC IsoId=Q28570-1; Sequence=Displayed;
CC Name=Alpha-2;
CC IsoId=Q28570-2; Sequence=Not described;
CC -!- DOMAIN: Composed of three domains: a modulating N-terminal domain, a
CC DNA-binding domain and a C-terminal ligand-binding domain.
CC -!- MISCELLANEOUS: [Isoform Alpha-2]: Does not bind thyroid hormone T3.
CC {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the nuclear hormone receptor family. NR1
CC subfamily. {ECO:0000305}.
