FunFam 633525: Dead box RNA helicase

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 3 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.
2 P15424 (/IDA) Q94C75 (/IDA)
ATP-dependent RNA helicase activity GO:0004004
Catalysis of the reaction: ATP + H2O = ADP + phosphate; this reaction drives the unwinding of an RNA helix.
1 P15424 (/IDA)
RNA strand annealing activity GO:0033592
Facilitates the base-pairing of complementary single-stranded RNA.

GO Term Annotations Evidence
Group I intron splicing GO:0000372
The splicing of Group I introns. This occurs by a ribozymic mechanism where the intron sequence forms a distinct 3D structure, characteristic of Group I introns and involved in determining the locations of the splice sites (there do not appear to be consensus splice site sequences) as well as having a role in catalyzing the splicing reactions, though protein factors are also required in vivo. Splicing occurs by a series of two transesterification reactions, generally with exogenous guanosine as the initiating nucleophile. The intron is excised as a linear piece (though it may subsequently circularize).
1 P15424 (/IMP)
Group II intron splicing GO:0000373
The splicing of Group II introns. This occurs by a ribozymic mechanism where the intron sequence forms a distinct 3D structure, characteristic of Group II introns and containing splice site consensus sequences, that is involved in catalyzing the splicing reactions, though protein factors are also required in vivo. Splicing occurs by a series of two transesterification reactions (mechanistically similar to those for splicing of nuclear mRNAs) initiated by a bulged adenosine residue within the intron sequence as the initiating nucleophile. The intron is excised as a lariat.

Transcription elongation from mitochondrial promoter GO:0006392
The extension of an RNA molecule after transcription initiation and promoter clearance at mitochondrial promoter by the addition of ribonucleotides catalyzed by a mitchondrial RNA polymerase.

Transcription elongation from mitochondrial promoter GO:0006392

Response to cold GO:0009409
Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a cold stimulus, a temperature stimulus below the optimal temperature for that organism.
1 Q94C75 (/IEP)
Response to water deprivation GO:0009414
Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a water deprivation stimulus, prolonged deprivation of water.
1 Q94C75 (/IMP)
Response to salt stress GO:0009651
Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating an increase or decrease in the concentration of salt (particularly but not exclusively sodium and chloride ions) in the environment.
1 Q94C75 (/IMP)
RNA folding GO:0034337
The process of assisting in the covalent and noncovalent assembly of single or multimeric RNAs into the correct tertiary structure.
