Enables

This protein enables 10 target(s):

Target	Category	Definition
p53 binding	molecular function	Binding to one of the p53 family of proteins. [GOC:hjd]
damaged DNA binding	molecular function	Binding to damaged DNA. [GOC:jl]
transcription coregulator activity	molecular function	A transcription regulator activity that modulates the transcription of specific gene sets via binding to a DNA-bound DNA-binding transcription factor, either on its own or as part of a complex. Coregulators often act by altering chromatin structure and modifications. For example, one class of transcription coregulators modifies chromatin structure through covalent modification of histones. A second class remodels the conformation of chromatin in an ATP-dependent fashion. A third class modulates interactions of DNA-bound DNA-binding transcription factors with other transcription coregulators. [GOC:txnOH-2018, PMID:10213677, PMID:16858867, PMID:24203923, PMID:25957681, Wikipedia:Transcription_coregulator]
protein binding	molecular function	Binding to a protein. [GOC:go_curators]
methylated histone binding	molecular function	Binding to a histone in which a residue has been modified by methylation. [GOC:bf, PMID:14585615]
telomeric DNA binding	molecular function	Binding to a telomere, a specific structure at the end of a linear chromosome required for the integrity and maintenance of the end. [GOC:jl, SO:0000624]
RNA polymerase II-specific DNA-binding transcription factor binding	molecular function	Binding to a sequence-specific DNA binding RNA polymerase II transcription factor, any of the factors that interact selectively and non-covalently with a specific DNA sequence in order to modulate transcription. [GOC:dph, GOC:vw]
ubiquitin-modified histone reader activity	molecular function	A molecular adaptor that recognizes and binds a histone protein containing a ubiquitination modification and that brings the target protein into contact with another protein to allow those proteins to function in a coordinated way. [GOC:dph, PMID:24526689]
histone reader activity	molecular function	A chromatin adaptor that recognizes specific forms of histones, either modified by a post-translational modification, or the unmodified form. Histone readers have roles in many processes, including in centromere function or in modulating the accessibility of cis-regulatory regions to the transcription machinery. [PMID:11498575, PMID:25688442, PMID:31082667, PMID:32260176, PMID:34726351]
histone binding	molecular function	Binding to a histone, any of a group of water-soluble proteins found in association with the DNA of eukaryotic or archaeal chromosomes. They are involved in the condensation and coiling of chromosomes during cell division and have also been implicated in gene regulation and DNA replication. They may be chemically modified (methylated, acetlyated and others) to regulate gene transcription. [GOC:jl, PMID:16209651, PMID:30212449, PMID:9305837]

Target	Category	Definition

nucleus	cellular component	A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. [GOC:go_curators]

replication fork	cellular component	The Y-shaped region of a replicating DNA molecule, resulting from the separation of the DNA strands and in which the synthesis of new strands takes place. Also includes associated protein complexes. [GOC:mah, ISBN:0198547684]
cytoplasm	cellular component	The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. [ISBN:0198547684]

site of double-strand break	cellular component	A region of a chromosome at which a DNA double-strand break has occurred. DNA damage signaling and repair proteins accumulate at the lesion to respond to the damage and repair the DNA to form a continuous DNA helix. [GOC:bf, GOC:mah, GOC:vw, PMID:20096808, PMID:21035408]

Involved In

This protein is involved in 13 target(s):

Target	Category	Definition
double-strand break repair via nonhomologous end joining	biological process	The repair of a double-strand break in DNA in which the two broken ends are rejoined with little or no sequence complementarity. Information at the DNA ends may be lost due to the modification of broken DNA ends. This term covers instances of separate pathways, called classical (or canonical) and alternative nonhomologous end joining (C-NHEJ and A-NHEJ). These in turn may further branch into sub-pathways, but evidence is still unclear. [GOC:rph, PMID:10827453, PMID:24837021]
chromatin organization	biological process	The assembly or remodeling of chromatin composed of DNA complexed with histones, other associated proteins, and sometimes RNA. [PMID:20404130]
DNA damage response	biological process	Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating damage to its DNA from environmental insults or errors during metabolism. [GOC:go_curators]
positive regulation of isotype switching	biological process	Any process that activates or increases the frequency, rate or extent of isotype switching. [GOC:go_curators]
positive regulation of DNA-templated transcription	biological process	Any process that activates or increases the frequency, rate or extent of cellular DNA-templated transcription. [GOC:go_curators, GOC:txnOH]
positive regulation of transcription by RNA polymerase II	biological process	Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter. [GOC:go_curators, GOC:txnOH]
positive regulation of DNA-binding transcription factor activity	biological process	Any process that activates or increases the frequency, rate or extent of activity of a transcription factor, any factor involved in the initiation or regulation of transcription. [GOC:ai]
protein homooligomerization	biological process	The process of creating protein oligomers, compounds composed of a small number, usually between three and ten, of identical component monomers. Oligomers may be formed by the polymerization of a number of monomers or the depolymerization of a large protein polymer. [GOC:ai]
cellular response to X-ray	biological process	Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of X-ray radiation. An X-ray is a form of electromagnetic radiation with a wavelength in the range of 10 nanometers to 100 picometers (corresponding to frequencies in the range 30 PHz to 3 EHz). [GOC:mah]
double-strand break repair via classical nonhomologous end joining	biological process	An instance of double-strand break repair via nonhomologous end joining that requires a number of factors important for V(D)J recombination, including the KU70/80 heterodimer (KU), XRCC4, ligase IV, and DNA-PKcs in mammals. It does not produce translocations (as opposed to the alternative nonhomologous end joining). [GOC:rph, PMID:18584027]
protein localization to site of double-strand break	biological process	Any process in which a protein is transported to, or maintained at, a region of a chromosome at which a DNA double-strand break has occurred. [GOC:mah, PMID:23080121]
