Summary
Enables G-quadruplex RNA binding activity. Involved in regulation of RNA splicing. Acts upstream of or within learning or memory and negative regulation of gene expression. Located in nuclear speck. Is expressed in several structures, including branchial arch; heart; limb; nervous system; and sensory organ. Human ortholog(s) of this gene implicated in X-linked intellectual developmental disorder 109. Orthologous to human AFF2 (AF4/FMR2 family member 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.
