Predicted to be a structural constituent of postsynaptic specialization. Involved in several processes, including modulation of chemical synaptic transmission; negative regulation of metabolic process; and nervous system development. Acts upstream of or within ephrin receptor signaling pathway. Located in postsynapse. Is active in calyx of Held. Is expressed in embryo. Used to study attention deficit hyperactivity disorder.

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.
