Background: DDX26/DICE1 is a member of the DEAD box family of proteins that possesses several conserved motifs which include the highly conserved DEAD (Asp-Glu-Ala-His) amino acid sequence motif. The major activity of DEAD box proteins is to function as ATP-dependent RNA helicases. RNA helicases play an important role in all aspects of RNA metabolism and function which include pre-mRNA splicing, RNA synthesis, RNA degradation, RNA export, RNA translation, RNA secondary structure formation, ribosome biogenesis, and the assembly of RNP complexes. DDX26/DICE1 is a subunit of the integrator complex involved in 3'-end processing of snRNAs. DDX26/DICE1 is implicated as a tumor suppressor, and its ectopic expression has been shown to inhibit tumor cell growth. Alternative names for DDX26/DICE1 include integrator complex subunit 6, Int6, protein deleted in cancer 1, protein DDX26, DBI-1, deleted in cancer 1, INTS6, DDX26A, HDB, Nochl2, and DKFZP434B105.
