Summary: Enables several functions, including Hsp70 protein binding activity; kinesin binding activity; and mitogen-activated protein kinase binding activity. Involved in several processes, including anterograde dendritic transport of messenger ribonucleoprotein complex; positive regulation of long-term synaptic depression; and positive regulation of nervous system development. Located in several cellular components, including cytoplasmic stress granule; dendritic shaft; and nuclear membrane. Part of protein-containing complex. Is active in glutamatergic synapse and postsynapse. Used to study microphthalmia. Orthologous to human STAU2 (staufen double-stranded RNA binding protein 2).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
