DICER1 Gene Information

HGNC symbol
DICER1 
Aliases
Dicer; HERNA; K12H4.8-LIKE; KIAA0928; MNG1 
Common name
dicer 1, ribonuclease III 
Entrez Id
23405
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.
