Deskripsi

The mechanisms that control the presynaptic abundance of GABAB receptors (GBRs) remains unclear. This study shows that sequence-related epitopes in APP, AJAP-1 and PIANP bind with nanomolar affinities to the N-terminal sushi-domain of presynaptic GBRs, and that selective loss of APP impaired GBR-mediated presynaptic inhibition and axonal GBR expression
