This gene encodes an estrogen receptor and ligand-activated transcription factor. The canonical protein contains an N-terminal ligand-independent transactivation domain, a central DNA binding domain, a hinge domain, and a C-terminal ligand-dependent transactivation domain. The protein localizes to the nucleus where it may form either a homodimer or a heterodimer with estrogen receptor 2. The protein encoded by this gene regulates the transcription of many estrogen-inducible genes that play a role in growth, metabolism, sexual development, gestation, and other reproductive functions and is expressed in many non-reproductive tissues. The receptor encoded by this gene plays a key role in breast cancer, endometrial cancer, and osteoporosis. This gene is reported to have dozens of transcript variants due to the use of alternate promoters and alternative splicing, however, the full-length nature of many of these variants remain uncertain.

Description
This track shows human genome high-confidence gene annotations from the
Consensus
Coding Sequence (CCDS) project. This project is a collaborative effort
to identify a core set of
human protein-coding regions that are consistently annotated and of high
quality. The long-term goal is to support convergence towards a standard set
of gene annotations on the human genome.
Collaborators include:
For more information on the different gene tracks, see our Genes FAQ.
Methods
CDS annotations of the human genome were obtained from two sources:
NCBI
RefSeq and a union of the gene annotations from
Ensembl and
Vega, collectively known
as Hinxton.
Genes with identical CDS genomic coordinates in both sets become CCDS
candidates. The genes undergo a quality evaluation, which must be approved by
all collaborators. The following criteria are currently used to assess each
gene:
- an initiating ATG (Exception: a non-ATG translation start codon is
annotated if it has sufficient experimental support), a valid stop codon, and
no in-frame stop codons (Exception: selenoproteins, which contain a TGA codon
that is known to be translated to a selenocysteine instead of functioning as
a stop codon)
- ability to be translated from the genome reference sequence without frameshifts
- recognizable splicing sites
- no intersection with putative pseudogene predictions
- supporting transcripts and protein homology
- conservation evidence with other species
A unique CCDS ID is assigned to the CCDS, which links together all gene
annotations with the same CDS. CCDS gene annotations are under continuous
review, with periodic updates to this track.
