Protein

ATP-dependent RNA helicase p62

Gene

Rm62

Organism
Drosophila melanogaster (Fruit fly)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

As an RNA helicase, unwinds RNA and alters RNA structures through ATP binding and hydrolysis. Involved in multiple cellular processes, including pre-mRNA splicing, alternative splicing, rRNA processing and miRNA processing, as well as transcription regulation (By similarity) (PubMed:12368261). Plays a role in innate immunity. Specifically restricts bunyavirus infection, including Rift Valley fever virus (RVFV) or La Crosse virus (LACV), but not vesicular stomatitis virus (VSV), in an interferon- and DROSHA-independent manner (PubMed:25126784).By similarity2 Publications
