Enables

This protein enables 12 target(s):

Target	Category	Definition
transcription cis-regulatory region binding	molecular function	Binding to a specific sequence of DNA that is part of a regulatory region that controls transcription of that section of the DNA. The transcribed region might be described as a gene, cistron, or operon. [GOC:txnOH]
DNA-binding transcription factor activity, RNA polymerase II-specific	molecular function	A DNA-binding transcription factor activity that modulates the transcription of specific gene sets transcribed by RNA polymerase II. [GOC:txnOH-2018]
DNA-binding transcription factor activity	molecular function	A transcription regulator activity that modulates transcription of gene sets via selective and non-covalent binding to a specific double-stranded genomic DNA sequence (sometimes referred to as a motif) within a cis-regulatory region. Regulatory regions include promoters (proximal and distal) and enhancers. Genes are transcriptional units, and include bacterial operons. [GOC:txnOH-2018]
nuclear receptor activity	molecular function	A DNA-binding transcription factor activity regulated by binding to a ligand that modulates the transcription of specific gene sets transcribed by RNA polymerase II. Nuclear receptor ligands are usually lipid-based (such as a steroid hormone) and the binding of the ligand to its receptor often occurs in the cytosol, which leads to its translocation to the nucleus. [GOC:txnOH-2018, PMID:23457262]
protein binding	molecular function	Binding to a protein. [GOC:go_curators]
zinc ion binding	molecular function	Binding to a zinc ion (Zn). [GOC:ai]
TBP-class protein binding	molecular function	Binding to a member of the class of TATA-binding proteins (TBP), including any of the TBP-related factors (TRFs). [GOC:jl, GOC:txnOH, http://www.mblab.gla.ac.uk/, PMID:16858867]
protein domain specific binding	molecular function	Binding to a specific domain of a protein. [GOC:go_curators]
chromatin DNA binding	molecular function	Binding to DNA that is assembled into chromatin. [GOC:mah]
thyroid hormone binding	molecular function	Binding to thyroxine (T4) or triiodothyronine (T3), tyrosine-based hormones produced by the thyroid gland. [GOC:rph]
general transcription initiation factor binding	molecular function	Binding to a general transcription initiation factor, a protein that contributes to transcription start site selection and transcription initiation. [GOC:txnOH-2018]
RNA polymerase II cis-regulatory region sequence-specific DNA binding	molecular function	Binding to a specific upstream regulatory DNA sequence (transcription factor recognition sequence or binding site) located in cis relative to the transcription start site (i.e., on the same strand of DNA) of a gene transcribed by RNA polymerase II. [GOC:txnOH-2018]

Located In

This protein is located in 3 target(s):

Target	Category	Definition

In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. [GOC:go_curators]
nucleoplasm	cellular component	That part of the nuclear content other than the chromosomes or the nucleolus. [GOC:ma, ISBN:0124325653]
cytosol	cellular component	The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. [GOC:hjd, GOC:jl]
