Summary
Enables molecular condensate scaffold activity; poly(U) RNA binding activity; and protein homodimerization activity. Predicted to be involved in central nervous system development; regulation of translation; and response to hormone. Located in cytoplasm and nucleus. Is expressed in central nervous system; gonad; gut; sensory organ; and skin. Orthologous to human MSI1 (musashi RNA binding protein 1). [provided by Alliance of Genome Resources, Nov 2024]
Expression
Biased expression in CNS E11.5 (RPKM 68.1), whole brain E14.5 (RPKM 37.5) and 9 other tissues See more

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.
