FunFam 65: RNA guanylyltransferase

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 2 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 guanylyltransferase activity GO:0008192
Catalysis of the posttranscriptional addition of a guanyl residue to the 5' end of an RNA molecule.
 2 O61120 (/IDA) Q381X9 (/IDA)
GMP binding GO:0019002
Interacting selectively and non-covalently with GMP, guanosine monophosphate.
 2 O61120 (/IDA) Q381X9 (/IDA)

There are 1 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
RNA capping GO:0036260
The sequence of enzymatic reactions by which a cap structure is added to the 5' end of a nascent RNA polymerase II transcript. All RNA polymerase II transcripts receive a 7-methyl-G cap. Then for (at least) small nuclear RNAs (snRNAs) and small nucleolar RNAs (snoRNAs), the7-methyl-G cap is hypermethylated to become a 2,2,7-trimethylguanosine (TMG) cap.
 2 O61120 (/IDA) Q381X9 (/IDA)

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
Cytoplasm GO:0005737
All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
