Enables RNA binding activity; protein domain specific binding activity; and ribonuclease III activity. Contributes to pre-miRNA binding activity. Involved in negative regulation of gene expression. Located in extracellular exosome and perinuclear region of cytoplasm. Part of RISC complex and RISC-loading complex. Implicated in DICER1 syndrome; gastrointestinal system cancer (multiple); multinodular goiter; nephroma; and pleuropulmonary blastoma. Biomarker of colorectal cancer; diffuse large B-cell lymphoma; and stomach cancer.
RGD Description
This gene encodes a protein possessing an RNA helicase motif containing a DEXH box in its amino terminus and an RNA motif in the carboxy terminus. The encoded protein functions as a ribonuclease and is required by the RNA interference and small temporal RNA (stRNA) pathways to produce the active small RNA component that represses gene expression. This protein also acts as a strong antiviral agent with activity against RNA viruses, including the Zika and SARS-CoV-2 viruses. Alternative splicing results in multiple transcript variants.
