FunFam 106: poly(A) RNA polymerase, mitochondrial

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 binding GO:0003723
Interacting selectively and non-covalently with an RNA molecule or a portion thereof.
1 O46102 (/ISS)
RNA adenylyltransferase activity GO:1990817
Catalysis of the template-independent extension of the 3'- end of an RNA strand by addition of one adenosine molecule at a time. Cannot initiate a chain 'de novo'. The primer, depending on the source of the enzyme, may be an RNA, or oligo(A) bearing a 3'-OH terminal group.
1 O46102 (/IMP)

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
MRNA polyadenylation GO:0006378
The enzymatic addition of a sequence of 40-200 adenylyl residues at the 3' end of a eukaryotic mRNA primary transcript.
1 O46102 (/ISS)
TRNA stabilization GO:0036416
Prevention of degradation of tRNA molecules.
1 O46102 (/IMP)
Mitochondrial mRNA polyadenylation GO:0097222
The enzymatic addition of a sequence of 40-60 adenylyl residues at the 3' end of a eukaryotic mitochondrial mRNA primary transcript. Mitochondria contain both stabilizing and destabilizing poly(A) tails.
1 O46102 (/IMP)

There are 2 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
Mitochondrion GO:0005739
A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration.
1 O46102 (/IDA)
Mitochondrion GO:0005739
A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration.
