FunFam 80: Small RNA degrading nuclease 3

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' exonuclease activity GO:0008408
Catalysis of the hydrolysis of ester linkages within nucleic acids by removing nucleotide residues from the 3' end.
2 A3KPE8 (/IDA) A3KPE8 (/IDA)
MiRNA binding GO:0035198
Interacting selectively and non-covalently with a microRNA, a 21-23 nucleotide RNA that is processed from a stem-loop RNA precursor (pre-miRNA) that is encoded within plant and animal genomes.
2 A3KPE8 (/IPI) A3KPE8 (/IPI)
3'-5'-exoribonuclease activity involved in mature miRNA 3'-end processing GO:0044748
Catalysis of the sequential cleavage of mononucleotides from a free 3' terminus of an RNA molecule that contributes to forming distinct miRNA isoforms from a mature miRNA.

There are 1 GO terms relating to "cellular component"

GO Term Annotations Evidence
Mediator complex GO:0016592
A protein complex that interacts with the carboxy-terminal domain of the largest subunit of RNA polymerase II and plays an active role in transducing the signal from a transcription factor to the transcriptional machinery. The mediator complex is required for activation of transcription of most protein-coding genes, but can also act as a transcriptional corepressor. The Saccharomyces complex contains several identifiable subcomplexes: a head domain comprising Srb2, -4, and -5, Med6, -8, and -11, and Rox3 proteins; a middle domain comprising Med1, -4, and -7, Nut1 and -2, Cse2, Rgr1, Soh1, and Srb7 proteins; a tail consisting of Gal11p, Med2p, Pgd1p, and Sin4p; and a regulatory subcomplex comprising Ssn2, -3, and -8, and Srb8 proteins. Metazoan mediator complexes have similar modular structures and include homologs of yeast Srb and Med proteins.
