FunFam 447: helicase SKI2W isoform X2

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 helicase activity GO:0003724
Catalysis of the reaction: ATP + H2O = ADP + phosphate; this reaction drives the unwinding of an RNA helix.
2 Q15477 (/TAS) Q15477 (/TAS)
Helicase activity GO:0004386
Catalysis of the reaction: ATP + H2O = ADP + phosphate, to drive the unwinding of a DNA or RNA helix.
2 Q9BI21 (/ISS) Q9VCH8 (/ISS)

There are 2 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
Regulation of alternative mRNA splicing, via spliceosome GO:0000381
Any process that modulates the frequency, rate or extent of alternative splicing of nuclear mRNAs.
2 Q9BI21 (/HMP) Q9VCH8 (/HMP)
Exonucleolytic catabolism of deadenylated mRNA GO:0043928
The chemical reactions and pathways resulting in the breakdown of the transcript body of a nuclear-transcribed mRNA that occurs when the ends are not protected by the 3'-poly(A) tail.
2 Q15477 (/TAS) Q15477 (/TAS)

There are 4 GO terms relating to "cellular component"

GO Term Annotations Evidence
Ski complex GO:0055087
A protein complex that regulates RNA degradation by the exosome complex. In Saccharomyces the complex has a heterotetrameric stoichiometry consisting of one copy each of Ski2p and Ski3 and two copies of Ski8p.
6 Q3TE28 (/ISO) Q3TW36 (/ISO) Q6NZR5 (/ISO) Q8C2W7 (/ISO) Q8CDP6 (/ISO) Q8R3X0 (/ISO)
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 Q9BI21 (/IC) Q9VCH8 (/IC)
Cytosol GO:0005829
The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
2 Q15477 (/TAS) Q15477 (/TAS)
Ski complex GO:0055087
A protein complex that regulates RNA degradation by the exosome complex. In Saccharomyces the complex has a heterotetrameric stoichiometry consisting of one copy each of Ski2p and Ski3 and two copies of Ski8p.
