Protein: LHFPL tetraspan subfamily member 4 protein (GABAA receptor regulatory Lhfpl4) (Lipoma HMGIC fusion partner-like 4 protein) (Q7Z7J7)
Organism: Homo sapiens (Human)
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:0000250|UniProtKB:Q7TSY2}. Postsynaptic cell membrane {ECO:0000250|UniProtKB:Q5U4E0}; Multi-pass membrane protein {ECO:0000255}. Note=Specifically localizes to inhibitory postsynaptic sites (By similarity). Colocalizes with GPHN, GABRG2 and NLGN2 at inhibitory postsynaptic sites (By similarity). {ECO:0000250|UniProtKB:Q5U4E0, ECO:0000250|UniProtKB:Q7TSY2}.
