FunFam 543: Pabp2, isoform B

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 6 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

MRNA splicing, via spliceosome GO:0000398

Positive regulation of protein glycosylation GO:0060050
Any process that activates or increases the frequency, rate or extent of the glycosylation of one or more amino acid residues within a protein. Protein glycosylation is the addition of a carbohydrate or carbohydrate derivative unit to a protein amino acid, e.g. the addition of glycan chains to proteins.

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
Nucleus GO:0005634
A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
2 Q7KNF2 (/HDA) Q7KNF2 (/HDA)
Nucleus GO:0005634
A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
2 Q7KNF2 (/IDA) Q7KNF2 (/IDA)
Cytoplasm GO:0005737
All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
2 Q7KNF2 (/IDA) Q7KNF2 (/IDA)
Precatalytic spliceosome GO:0071011
A spliceosomal complex that is formed by the recruitment of a preassembled U5-containing tri-snRNP to the prespliceosome. Although all 5 snRNPs are present, the precatalytic spliceosome is catalytically inactive. The precatalytic spliceosome includes many proteins in addition to those found in the associated snRNPs.
2 Q7KNF2 (/HDA) Q7KNF2 (/HDA)
Catalytic step 2 spliceosome GO:0071013
A spliceosomal complex that contains three snRNPs, including U5, bound to a splicing intermediate in which the first catalytic cleavage of the 5' splice site has occurred. The precise subunit composition differs significantly from that of the catalytic step 1, or activated, spliceosome, and includes many proteins in addition to those found in the associated snRNPs.
2 Q7KNF2 (/HDA) Q7KNF2 (/HDA)
Nucleus GO:0005634
A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing.
