Staufen, RNA binding protein, homolog 2
Stau2, 39K2, Staufen 2
Staufen homolog 2 is a member of the family of double-stranded RNA (dsRNA)-binding proteins involved in the transport and/or localization of mRNAs to different subcellular compartments and/or organelles. These proteins are characterized by the presence of multiple dsRNA-binding domains which are required to bind RNAs having double-stranded secondary structures. Staufen homolog 2 shares 48.5% and 59.9% similarity with drosophila and human staufen, respectively. The exact function of Staufen homolog 2 is not known, but since it contains 3 copies of conserved dsRNA binding domain, it could be involved in double-stranded RNA binding events. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2009] (from
STAU1 & STAU2 & ELAVL1 mRNAs & proteins were detected throughout cow preimplantation development from the germinal vesicle (GV) oocyte to the blastocyst stage; ELAVL2 mRNAs were detectable from the GV to the morula stage; ELAVL2 protein was in all stages

Staufen 1 and Staufen2 are novel and ubiquitous stress granules components that are involved in repositioning of most polysomal mRNAs, but not of recently synthesized transcripts, during the stress response
