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).

Here, we report that chronic treatment in adult mouse with Fasudil, is able to counteract vertical and horizontal hyperactivities, restores recognition memory and limits the brain ventricular dilatation observed in Ophn1(-)(/y) However, deficits in working and spatial memories are partially or not rescued by the treatment

Furthermore, we found that olfactory behaviour was perturbed in OPHN1 ko mice. Chronic treatment with a Rho kinase inhibitor rescued most of the defects of the newly generated neurons. Altogether, our data indicated that OPHN1 plays a key role in regulating the number, morphology and function of adult-born inhibitory interneurons and contributed to identify potential therapeutic targets.

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.
