The ARHGAP32 isoform PX-RICS is specifically targeted to inhibitory synapses by binding to gephyrin.
Gephyrin is identified as the primary synaptic anchor for PX-RICS and the N-terminal gephyrin-binding region (GBR) engages gephyrin E-domain through conserved hydrophobic interactions, explaining the isoform-specific targeting of PX-RICS (but not RICS) to inhibitory synapses.
