RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

mRNA and Protein(s)

NM_001017960.2 → NP_001017960.1 thyroid hormone receptor alpha isoform TRalpha1

See identical proteins and their annotated locations for NP_001017960.1

Status: VALIDATED

Description

Transcript Variant: This variant (TRalpha1) differs in the 3' UTR and coding region compared to TRalpha2, resulting in a shorter isoform (TRalpha1) with a distinct C-terminus. The TRalpha1 isoform, also known as c-erbAalpha1, functions as a thyroid hormone-dependent transcription factor.

See identical proteins and their annotated locations for NP_112396.2

Status: VALIDATED

Description

Transcript Variant: This variant (TRalpha2) contains an alternate 3' terminal exon compared to variant TRalpha1. The resulting protein (c-erbAalpha2, also known as TRalpha 2) has a distinct C-terminus compared to isoform TRalpha1, and fails to bind thyroid hormones or to trans-activate thyroid hormone responsive genes.
