FunFam 642: Zinc finger with KRAB and SCAN domains 2

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 12 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
DNA-binding transcription factor activity, RNA polymerase II-specific GO:0000981
A protein or a member of a complex that interacts selectively and non-covalently with a specific DNA sequence (sometimes referred to as a motif) within the regulatory region of a RNA polymerase II-transcribed gene to modulate transcription. Regulatory regions include promoters (proximal and distal) and enhancers. Genes are transcriptional units.

DNA-binding transcription factor activity, RNA polymerase II-specific GO:0000981
A protein or a member of a complex that interacts selectively and non-covalently with a specific DNA sequence (sometimes referred to as a motif) within the regulatory region of a RNA polymerase II-transcribed gene to modulate transcription. Regulatory regions include promoters (proximal and distal) and enhancers. Genes are transcriptional units.
1 Q63HK3 (/ISM)
DNA-binding transcription repressor activity, RNA polymerase II-specific GO:0001227
A protein or a member of a complex that interacts selectively and non-covalently with a specific DNA sequence (sometimes referred to as a motif) within the regulatory region of a RNA polymerase II-transcribed gene to repress or decrease transcription. Regulatory regions include promoters (proximal and distal) and enhancers. Genes are transcriptional units.
1 Q9BRR0 (/IDA)
DNA binding GO:0003677
Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
1 Q9BRR0 (/IDA)
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 Q9BRR0 (/IDA)
DNA-binding transcription factor activity GO:0003700
A protein or a member of a complex that interacts selectively and non-covalently with a specific DNA sequence (sometimes referred to as a motif) within the regulatory region of a gene to modulate transcription. Regulatory regions include promoters (proximal and distal) and enhancers. Genes are transcriptional units, and include bacterial operons.
1 Q9BRR0 (/IDA)
DNA-binding transcription factor activity GO:0003700
A protein or a member of a complex that interacts selectively and non-covalently with a specific DNA sequence (sometimes referred to as a motif) within the regulatory region of a gene to modulate transcription. Regulatory regions include promoters (proximal and distal) and enhancers. Genes are transcriptional units, and include bacterial operons.
1 Q9Y2L8 (/NAS)
Zinc ion binding GO:0008270
Interacting selectively and non-covalently with zinc (Zn) ions.
1 Q9Y2L8 (/NAS)
Sequence-specific DNA binding GO:0043565
Interacting selectively and non-covalently with DNA of a specific nucleotide composition, e.g. GC-rich DNA binding, or with a specific sequence motif or type of DNA e.g. promotor binding or rDNA binding.

There are 7 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 Q9BRR0 (/IDA)
Regulation of transcription, DNA-templated GO:0006355
Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.
1 Q9Y2L8 (/NAS)
Lysosome organization GO:0007040
A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a lysosome. A lysosome is a cytoplasmic, membrane-bounded organelle that is found in most animal cells and that contains a variety of hydrolases.
1 Q9BRR0 (/IMP)
Negative regulation of autophagy GO:0010507
Any process that stops, prevents, or reduces the frequency, rate or extent of autophagy. Autophagy is the process in which cells digest parts of their own cytoplasm.
