The name of this superfamily has been modified since the most recent official CATH+ release (v4_4_0). At the point of the last release, this superfamily was named:

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

FunFam 7: 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.
2 A2A5N3 (/TAS) B2RXY9 (/TAS)

There are 7 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
Oocyte maturation GO:0001556
A developmental process, independent of morphogenetic (shape) change, that is required for an oocyte to attain its fully functional state. Oocyte maturation commences after reinitiation of meiosis commonly starting with germinal vesicle breakdown, and continues up to the second meiotic arrest prior to fertilization.
2 A2A5N3 (/IDA) B2RXY9 (/IDA)
Oocyte maturation GO:0001556
A developmental process, independent of morphogenetic (shape) change, that is required for an oocyte to attain its fully functional state. Oocyte maturation commences after reinitiation of meiosis commonly starting with germinal vesicle breakdown, and continues up to the second meiotic arrest prior to fertilization.
2 A2A5N3 (/IMP) B2RXY9 (/IMP)
Chromatin remodeling GO:0006338
Dynamic structural changes to eukaryotic chromatin occurring throughout the cell division cycle. These changes range from the local changes necessary for transcriptional regulation to global changes necessary for chromosome segregation.
2 A2A5N3 (/IDA) B2RXY9 (/IDA)
Chromatin remodeling GO:0006338
Dynamic structural changes to eukaryotic chromatin occurring throughout the cell division cycle. These changes range from the local changes necessary for transcriptional regulation to global changes necessary for chromosome segregation.
2 A2A5N3 (/IMP) B2RXY9 (/IMP)
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.
2 A2A5N3 (/IMP) B2RXY9 (/IMP)
Chromatin-mediated maintenance of transcription GO:0048096
Maintenance of transcription by remodelling of chromatin into an 'open configuration'. Once established, this regulation is mitotically stable and is maintained over many cell divisions. It is also heritable.
2 A2A5N3 (/IMP) B2RXY9 (/IMP)
Nucleus localization GO:0051647
Any process in which the nucleus is transported to, and/or maintained in, a specific location within the cell.
2 A2A5N3 (/IMP) B2RXY9 (/IMP)

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
Extracellular exosome GO:0070062
A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.
