Plays a role in the regulation of inhibitory synapse formation and function by being involved in maintening gamma-aminobutyric acid receptors (GABAARs) clustering and their associated scaffold proteins at inhibitory synaptic sites. Acts in concert with NLGN2 to recruit or stabilize GABAARs.
Subcellular locations: Cell projection, Dendrite, Postsynaptic cell membrane
Specifically localizes to inhibitory postsynaptic sites (By similarity). Colocalizes with GPHN, GABRG2 and NLGN2 at inhibitory postsynaptic sites (By similarity).
