Protein: LHFPL tetraspan subfamily member 4 protein (Lipoma HMGIC fusion partner-like 4 protein) (Q7TSY2)
Organism: Rattus norvegicus (Rat)
Function: 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 location: Cell projection, dendrite {ECO:0000269|PubMed:28978485}. Postsynaptic cell membrane {ECO:0000269|PubMed:28978485, ECO:0000269|PubMed:29742426}; Multi-pass membrane protein {ECO:0000255}. Note=Specifically localizes to inhibitory postsynaptic sites (PubMed:29742426). Colocalizes with GPHN, GABRG2 and NLGN2 at inhibitory postsynaptic sites (PubMed:28978485, PubMed:29742426). {ECO:0000269|PubMed:28978485, ECO:0000269|PubMed:29742426}.
