The name of this superfamily has been modified since the most recent official CATH+ release (v4_2_0). At the point of the last release, this superfamily was named:

"
Ribonuclease III domain

FunFam 2103: Ribonuclease III

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
RNA-directed 5'-3' RNA polymerase activity GO:0003968
Catalysis of the reaction: nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1); uses an RNA template, i.e. the catalysis of RNA-template-directed extension of the 3'-end of an RNA strand by one nucleotide at a time.
1 A0A1D8PM62 (/IDA)
RNA-directed 5'-3' RNA polymerase activity GO:0003968
Catalysis of the reaction: nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1); uses an RNA template, i.e. the catalysis of RNA-template-directed extension of the 3'-end of an RNA strand by one nucleotide at a time.
1 A0A1D8PM62 (/IMP)
Ribonuclease III activity GO:0004525
Catalysis of the endonucleolytic cleavage of RNA with 5'-phosphomonoesters and 3'-OH termini; makes two staggered cuts in both strands of dsRNA, leaving a 3' overhang of 2 nt.
1 A0A1D8PM62 (/TAS)

There are 3 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
RRNA processing GO:0006364
Any process involved in the conversion of a primary ribosomal RNA (rRNA) transcript into one or more mature rRNA molecules.
1 A0A1D8PM62 (/IMP)
Production of siRNA involved in RNA interference GO:0030422
Cleavage of double-stranded RNA to form small interfering RNA molecules (siRNAs) of 21-23 nucleotides, in the context of RNA interference.
1 A0A1D8PM62 (/IDA)
Production of miRNAs involved in gene silencing by miRNA GO:0035196
Cleavage of stem-loop RNA precursors into microRNAs (miRNAs), a class of small RNAs that primarily silence genes by blocking the translation of mRNA transcripts into protein.
1 A0A1D8PM62 (/TAS)
