DDX50 is an ATP-dependent RNA helicase with dual roles in RNA metabolism and innate immunity. Primary function involves RNA processing, including participation in pre-mRNA splicing and ribosomal RNA production 1. Additionally, DDX50 functions as a viral restriction factor that activates interferon signaling 2. Mechanistically, DDX50 promotes IRF3 and NF-κB activation following viral RNA stimulation or infection with RNA and DNA viruses, acting via the TICAM1 adapter independently of the DDX1-DDX21-DHX36 complex 2. DDX50 decreases replication of vaccinia virus, herpes simplex virus, Zika virus, and dengue virus during early infection stages by upregulating interferon-beta production 32. Recently, DDX50 was shown to cooperate with STAU1 in a glucose-dependent manner to stabilize pro-differentiation RNAs (JUN, OVOL1, CEBPB, PRDM1, TINCR), redirecting STAU1 from mRNA decay to RNA stabilization pathways 4. Disease relevance includes potential associations with optic disc drusen 5 and asthenozoospermia 6. Clinically, DDX50's antiviral functions suggest therapeutic potential for viral infections, while its role in cellular differentiation indicates broader biomedical significance.
