The name of this superfamily has been modified since the most recent official CATH+ release (v4_3_0). At the point of the last release, this superfamily was named:

"
Zinc/RING finger domain, C3HC4 (zinc finger)
".

FunFam 526: PHD and ring finger domains 1

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 5 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
Zinc ion binding GO:0008270
Interacting selectively and non-covalently with zinc (Zn) ions.
4 A0A0B4KF97 (/ISM) O94400 (/ISM) Q6NP07 (/ISM) Q9VNE0 (/ISM)
RNA polymerase binding GO:0070063
Interacting selectively and non-covalently with an RNA polymerase molecule or complex.
3 A6H619 (/ISS) Q9P1Y6 (/ISS) Q9P1Y6 (/ISS)
Protein domain specific binding GO:0019904
Interacting selectively and non-covalently with a specific domain of a protein.
1 A6H619 (/ISO)
Ubiquitin protein ligase activity GO:0061630
Catalysis of the transfer of ubiquitin to a substrate protein via the reaction X-ubiquitin + S -> X + S-ubiquitin, where X is either an E2 or E3 enzyme, the X-ubiquitin linkage is a thioester bond, and the S-ubiquitin linkage is an amide bond: an isopeptide bond between the C-terminal glycine of ubiquitin and the epsilon-amino group of lysine residues in the substrate or, in the linear extension of ubiquitin chains, a peptide bond the between the C-terminal glycine and N-terminal methionine of ubiquitin residues.

RNA polymerase binding GO:0070063
Interacting selectively and non-covalently with an RNA polymerase molecule or complex.

There are 5 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
Regulation of alternative mRNA splicing, via spliceosome GO:0000381
Any process that modulates the frequency, rate or extent of alternative splicing of nuclear mRNAs.
3 A0A0B4KF97 (/HMP) Q6NP07 (/HMP) Q9VNE0 (/HMP)
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 O94400 (/ISO)
Transcription by RNA polymerase II GO:0006366
The synthesis of RNA from a DNA template by RNA polymerase II (RNAP II), originating at an RNA polymerase II promoter. Includes transcription of messenger RNA (mRNA) and certain small nuclear RNAs (snRNAs).
1 A6H619 (/ISO)
MRNA processing GO:0006397
Any process involved in the conversion of a primary mRNA transcript into one or more mature mRNA(s) prior to translation into polypeptide.
1 A6H619 (/ISO)
Protein modification by small protein conjugation or removal GO:0070647
A protein modification process in which one or more groups of a small protein, such as ubiquitin or a ubiquitin-like protein, are covalently attached to or removed from a target protein.

There are 4 GO terms relating to "cellular component"

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
Nucleus GO:0005634
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.
3 A0A0B4KF97 (/IC) Q6NP07 (/IC) Q9VNE0 (/IC)
Membrane GO:0016020
A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
2 Q9P1Y6 (/HDA) Q9P1Y6 (/HDA)
Nucleus GO:0005634
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.
1 O94400 (/HDA)
Cytosol GO:0005829
The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
