Description

Description: homeobox containing 1 [Source:HGNC Symbol;Acc:HGNC:26137]
Entrez Summary Enables double-stranded telomeric DNA binding activity; identical protein binding activity; and sequence-specific double-stranded DNA binding activity. Involved in negative regulation of transcription by RNA polymerase II; positive regulation of telomerase activity; and positive regulation of telomere maintenance via telomerase. Located in several cellular components, including centrosome; chromosome, telomeric region; and nuclear body. [provided by Alliance of Genome Resources, Apr 2022]

Previous Annotations

Source Annotation
TF-CAT classification No
PMIDS:
Vaquerizas 2009 TF classification
"a" Has direct evidence of TF function;
"b" Has evidence for an orthologous TF;
"c" contains likely DBDs, but has no functional evidence;
"x" is an unlikely TF such as predicted gene, genes with likely non-specific DBDs or that have function outside transcription;
"other" category contains proteins without clear DBDs they curated from external sources.
b
CisBP considers it as a TF? Yes
TFclass considers it as a TF? Yes
Has GO:0003700 "transcription factor activity, sequence-specific DNA binding" No
GO-Info
Initial Assessment
1a1 Protein has a high confidence PWM (HT-SELEX, PBM or B1H model) or there is a crystal structure that supports sequence specific DNA binding;
1a2 There is high confidence data for a close ortholog (as defined in CisBP);
2a1 There is lower confidence direct evidence, such as a Jaspar, Hocomoco or Transfac model;
2a2 There is lower confidence evidence for an close ortholog;
3a There is decent circumstantial evidence for its role as a TF or not;
4a Two or more datasets predict it as a TF;
5a One of the source datasets predicts is as a TF
1a1, Direct HQ evidence
TF has conditional DNA-binding requirements
