    Summary
    Enables identical protein binding activity. Involved in postsynaptic specialization organization. Located in neuronal cell body and postsynaptic membrane. Is active in glutamatergic synapse. Is extrinsic component of postsynaptic density membrane. Human ortholog(s) of this gene implicated in syndromic X-linked mental retardation Hough type. Orthologous to human CNKSR2 (connector enhancer of kinase suppressor of Ras 2). [provided by Alliance of Genome Resources, Dec 2024]

    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.
