FunFam 6: 5'-3' exoribonuclease

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 1 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
5'-3' exoribonuclease activity GO:0004534
Catalysis of the sequential cleavage of mononucleotides from a free 5' terminus of an RNA molecule.
 1 Q9FQ02 (/IDA)

There are 4 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
MiRNA catabolic process GO:0010587
The chemical reactions and pathways resulting in the breakdown of miRNA, microRNA, a class of single-stranded RNA molecules of about 21-23 nucleotides in length, which regulates gene expression.
 2 F4K1L3 (/IMP) Q9FQ02 (/IMP)
RRNA 5'-end processing GO:0000967
Any process involved in forming the mature 5' end of an rRNA molecule.
 1 Q9FQ02 (/IMP)
Negative regulation of posttranscriptional gene silencing GO:0060149
Any process that decreases the frequency, rate or extent of the inactivation of gene expression by a posttranscriptional mechanism.
 1 Q9FQ02 (/IMP)
Nuclear polyadenylation-dependent rRNA catabolic process GO:0071035
The chemical reactions and pathways occurring in the nucleus and resulting in the breakdown of a ribosomal RNA (rRNA) molecule, including RNA fragments released as part of processing the primary transcript into multiple mature rRNA species, initiated by the enzymatic addition of a sequence of adenylyl residues (polyadenylation) at the 3' end the target rRNA.
 1 Q9FQ02 (/IMP)

There are 1 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.
