Protein

ATP-dependent RNA helicase DHX8

Gene

DHX8

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Involved in pre-mRNA splicing as component of the spliceosome (PubMed:11991638, PubMed:28502770, PubMed:28076346). Facilitates nuclear export of spliced mRNA by releasing the RNA from the spliceosome (PubMed:8608946).4 Publications

Catalytic activityi

ATP + H2O = ADP + phosphate.
