Helicase MOV-10 is a 5'-3' RNA helicase required for RNA-mediated gene silencing by the RNA-induced silencing complex (RISC) [1-3]. It is involved in mRNA metabolism and translation, modulation of viral infectivity, inhibition of retrotransposition and regulation of synaptic transmission [4]. It interacts with FMRP1 and regulates miRNA-mediated translational repression by AGO2 [5]. This is a presumed helical domain found between Pfam:PF21633 and Pfam:PF21634.
