The name of this superfamily has been modified since the most recent official CATH+ release (v4_3_0). At the point of the last release, this superfamily was named:

"
c-terminal domain of poly(a) binding protein

FunFam 11: Polyadenylate-binding protein

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
Poly(A) binding GO:0008143
Interacting selectively and non-covalently with a sequence of adenylyl residues in an RNA molecule, such as the poly(A) tail, a sequence of adenylyl residues at the 3' end of eukaryotic mRNA.
1 P31209 (/IDA)

There are 6 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 3'-end processing GO:0031124
Any process involved in forming the mature 3' end of an mRNA molecule.
1 P31209 (/ISO)
Regulation of nuclear-transcribed mRNA poly(A) tail shortening GO:0060211
Any process that modulates the frequency, rate or extent of poly(A) tail shortening of a nuclear-transcribed mRNA. Poly(A) tail shortening is the decrease in length of the poly(A) tail of an mRNA from full length to an oligo(A) length.
1 P31209 (/IDA)
Negative regulation of nuclear-transcribed mRNA poly(A) tail shortening GO:0060212
Any process that decreases the frequency, rate or extent of poly(A) tail shortening of a nuclear-transcribed mRNA. Poly(A) tail shortening is the decrease in length of the poly(A) tail of an mRNA from full length to an oligo(A) length.
1 P31209 (/IDA)
Negative regulation of exoribonuclease activity GO:1901918
Any process that stops, prevents or reduces the frequency, rate or extent of exoribonuclease activity.
1 P31209 (/IDA)
Positive regulation of exoribonuclease activity GO:1901919
Any process that activates or increases the frequency, rate or extent of exoribonuclease activity.
1 P31209 (/IDA)
Positive regulation of cytoplasmic translational initiation GO:1904690
Any process that activates or increases the frequency, rate or extent of cytoplasmic translational initiation.
1 P31209 (/ISO)

There are 4 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.
1 P31209 (/IDA)
Cytosol GO:0005829
The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
1 P31209 (/HDA)
Cytoplasmic stress granule GO:0010494
A dense aggregation in the cytosol composed of proteins and RNAs that appear when the cell is under stress.
1 P31209 (/IDA)
Post-mRNA release spliceosomal complex GO:0071014
A spliceosomal complex that is formed following the release of the spliced product from the post-spliceosomal complex and contains the excised intron and three snRNPs, including U5.
