Summary: Enables lncRNA binding activity and mRNA 3'-UTR binding activity. Involved in several processes, including pole plasm assembly; positive regulation of cellular component biogenesis; and regulation of pole plasm oskar mRNA localization. Located in several cellular components, including basal cortex; cytoplasmic ribonucleoprotein granule; and posterior cell cortex. Is active in cytoplasmic ribonucleoprotein granule. Is expressed in several structures, including embryonic/larval midgut primordium; ganglia; germline cell; gut section; and head epidermis primordium. Orthologous to several human genes including STAU2 (staufen double-stranded RNA binding protein 2). [provided by Alliance of Genome Resources, Dec 2024]

Study shows that double-stranded RNA binding domains (dsRBDs) 1 and 2 of mStau2 bind RNA with similar affinities and kinetics as dsRBDs 3 and 4. While RNA binding by these tandem domains is transient, all four dsRBDs recognize their target RNAs with high stability. Rescue experiments in Drosophila oocytes demonstrate that mStau2 partially rescues dmStau-dependent mRNA localization.

the expression of Adf-1 targets Staufen and Fasciclin II (FasII), identified through larval brain ChIP-Seq for Adf-1, is negatively regulated by Adf-1, and manipulations of these genes predictably modify dendrite growth.

Data propose bicoid mRNA localization was done by Swallow indirectly organizing the cytoskeleton, whereas Staufen plays a direct role in dynein-dependent bicoid mRNA transport.
