FunFam 91: host cell factor 1 isoform X3

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 7 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Chromatin binding GO:0003682
Interacting selectively and non-covalently with chromatin, the network of fibers of DNA, protein, and sometimes RNA, that make up the chromosomes of the eukaryotic nucleus during interphase.
1 P51610 (/IDA)
Transcription coactivator activity GO:0003713
A protein or a member of a complex that interacts specifically and non-covalently with a DNA-bound DNA-binding transcription factor to activate the transcription of specific genes. Coactivators 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 ATP-dependent class modifies the conformation of chromatin. Another type of coregulator activity is the bridging of a DNA-binding transcription factor to the basal transcription machinery. The Mediator complex, which bridges transcription factors and RNA polymerase, is also a transcription coactivator.
1 P51610 (/IMP)
Protein binding GO:0005515
Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
1 P51610 (/IPI)
Protein binding, bridging GO:0030674
The binding activity of a molecule that brings together two or more protein molecules, or a protein and another macromolecule or complex, through a selective, non-covalent, often stoichiometric interaction, permitting those molecules to function in a coordinated way.
1 P51610 (/IPI)
Activating transcription factor binding GO:0033613
Interacting selectively and non-covalently with an activating transcription factor, any protein whose activity is required to initiate or upregulate transcription.
1 P51610 (/IPI)
Identical protein binding GO:0042802
Interacting selectively and non-covalently with an identical protein or proteins.
1 P51610 (/IPI)
Cadherin binding GO:0045296
Interacting selectively and non-covalently with cadherin, a type I membrane protein involved in cell adhesion.
1 P51610 (/HDA)

There are 13 GO terms relating to "biological process"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Negative regulation of transcription by RNA polymerase II GO:0000122
Any process that stops, prevents, or reduces the frequency, rate or extent of transcription mediated by RNA polymerase II.
1 P51610 (/ISS)
Regulation of transcription, DNA-templated GO:0006355
Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.
1 P51610 (/IDA)
Mitochondrion organization GO:0007005
A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a mitochondrion; includes mitochondrial morphogenesis and distribution, and replication of the mitochondrial genome as well as synthesis of new mitochondrial components.
1 P51610 (/TAS)
Positive regulation of gene expression GO:0010628
Any process that increases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.
1 P51610 (/IDA)
Protein deubiquitination GO:0016579
The removal of one or more ubiquitin groups from a protein.
1 P51610 (/TAS)
Release from viral latency GO:0019046
The process by which a virus begins to replicate following a latency replication decision (switch).
1 P51610 (/NAS)
Regulation of protein complex assembly GO:0043254
Any process that modulates the frequency, rate or extent of protein complex assembly.
1 P51610 (/IDA)
Histone H4-K5 acetylation GO:0043981
The modification of histone H4 by the addition of an acetyl group to a lysine residue at position 5 of the histone.
1 P51610 (/IDA)
Histone H4-K8 acetylation GO:0043982
The modification of histone H4 by the addition of an acetyl group to a lysine residue at position 8 of the histone.

Any process that activates or increases the rate or extent of progression through the cell cycle.
1 P51610 (/TAS)
