The function of LHFPL4 (LHFPL tetraspan subfamily member 4, Ensembl gene identifier ENSG00000156959) is as follows. 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. .
