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:

"
Ribonuclease H-like superfamily/Ribonuclease H

FunFam 195: Chromosome 1, whole genome shotgun sequence

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 3 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
3'-5'-exoribonuclease activity GO:0000175
Catalysis of the sequential cleavage of mononucleotides from a free 3' terminus of an RNA molecule.
1 Q08I43 (/IMP)
Double-stranded RNA binding GO:0003725
Interacting selectively and non-covalently with double-stranded RNA.
1 Q08I43 (/IDA)
Double-stranded RNA-specific ribonuclease activity GO:0032296
Catalysis of the hydrolysis of phosphodiester bonds in double-stranded RNA molecules.
1 Q08I43 (/IDA)

There are 2 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
Exonucleolytic trimming to generate mature 3'-end of 5.8S rRNA from tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA) GO:0000467
Exonucleolytic digestion of a pre-rRNA molecule to generate the mature 3'-end of a 5.8S rRNA molecule derived from an originally tricistronic pre-rRNA transcript that contained the Small Subunit (SSU) rRNA, the 5.8S rRNA, and the Large Subunit (LSU) rRNA in that order from 5' to 3' along the primary transcript.
1 Q08I43 (/IMP)
Negative regulation of chromatin silencing by small RNA GO:0060906
Any process that decreases the frequency, rate or extent of chromatin silencing by small RNA. Chromatin silencing by small RNA is the repression of transcription by conversion of large regions of DNA into heterochromatin, directed by small RNAs sharing sequence identity to the repressed region.
1 Q08I43 (/IMP)

There are 3 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.
1 Q08I43 (/ISS)
Cytoplasm GO:0005737
All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
1 Q08I43 (/IDA)
Cytosol GO:0005829
The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
1 Q08I43 (/HDA)
