Summary: Predicted to enable several functions, including ATP binding activity; molecular condensate scaffold activity; and signaling adaptor activity. Involved in positive regulation of dendritic spine morphogenesis. Acts upstream of or within generation of neurons; intracellular mRNA localization; and synapse assembly. Located in cytoplasmic stress granule. Is active in dendrite and synapse. Is expressed in central nervous system; eye; and genitourinary system. Orthologous to human CAPRIN1 (cell cycle associated protein 1). [provided by Alliance of Genome Resources, Jan 2025]

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.
