    Summary
    Enables GTPase activator activity and actin binding activity. Involved in negative regulation of proteasomal protein catabolic process. Acts upstream of or within several processes, including regulation of endocytosis; regulation of glutamatergic synaptic transmission; and synaptic vesicle endocytosis. Located in several cellular components, including actin cytoskeleton; dendritic spine; and terminal bouton. Is expressed in several structures, including central nervous system; lung; metanephros; retina; and thymus. Used to study syndromic intellectual disability. Human ortholog(s) of this gene implicated in X-linked mental retardation with cerebellar hypoplasia and distinctive facial appearance. Orthologous to human OPHN1 (oligophrenin 1).

    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.
