Oligophrenin-1 (OPHN1)

Stimulates GTP hydrolysis of All 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.

Crucial for the stabilization of AMPA receptors at postsynaptic sites. Critical for the regulation of synaptic vesicle endocytosis at presynaptic terminals.
