UniProtKB - O60890 (OPHN1_HUMAN)

Protein

Oligophrenin-1

Gene

OPHN1

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Stimulates GTP hydrolysis of members of the Rho family. Its action on RHOA activity and signaling is implicated in growth and stabilization of dendritic spines, and therefore in synaptic function. Critical for the stabilization of AMPA receptors at postsynaptic sites. Critical for the regulation of synaptic vesicle endocytosis at presynaptic terminals. Required for the localization of NR1D1 to dendrites, can suppress its repressor activity and protect it from proteasomal degradation (By similarity).By similarity

Involvement in diseasei

Mental retardation, X-linked, syndromic, OPHN1-related (MRXSO)3 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. MRXSO patients manifest mental retardation associated with cerebellar hypoplasia and distinctive facial dysmorphism.
