Summaries for THRA Gene

Entrez Gene Summary for THRA Gene

  • The protein encoded by this gene is a nuclear hormone receptor for triiodothyronine. It is one of the several receptors for thyroid hormone, and has been shown to mediate the biological activities of thyroid hormone. Knockout studies in mice suggest that the different receptors, while having certain extent of redundancy, may mediate different functions of thyroid hormone. Alternatively spliced transcript variants encoding distinct isoforms have been reported. [provided by RefSeq, Jul 2008]

GeneCards Summary for THRA Gene

THRA (Thyroid Hormone Receptor, Alpha) is a Protein Coding gene. Diseases associated with THRA include hypothyroidism, congenital, nongoitrous, 6 and peripheral resistance to thyroid hormones. Among its related pathways are Endochondral Ossification and Development NOTCH1-mediated pathway for NF-KB activity modulation. GO annotations related to this gene include sequence-specific DNA binding transcription factor activity and transcription factor binding. An important paralog of this gene is NR1I2.

UniProtKB/Swiss-Prot for THRA Gene

  • Nuclear hormone receptor that can act as a repressor or activator of transcription. High affinity receptor for thyroid hormones, including triiodothyronine and thyroxine.
