MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is an integral membrane protein involved in gamma-aminobutyric acid (GABA) and glycine uptake into synaptic vesicles. The encoded protein is a member of amino acid/polyamine transporter family II. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygous null mice been independently reported to die perinatally exhibiting a hunched posture, respiratory failure, cleft secondary palate due to failure of palate shelf elevation, umbilical hernia or omphalocele, and loss of neurotransmitter release in both GABAergic and glycinergic neurons.
