Putative ATP-dependent RNA helicase ECM32

Gene

ECM32

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Probable RNA helicase, which may be involved in modulation of the translation termination process. Probably unwinds double-stranded RNA. In vitro, unwinds covalently closed, circular DNA in the presence of a DNA topoisomerase TOP1 and replication factor-A protein RFA1.2 Publications

Catalytic activityi

ATP + H2O = ADP + phosphate.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
