"Long-term depression (LTD) is a long-lasting activity-dependent decrease in synaptic strength. NMDA receptor ( NMDAR) dependent LTD, an extensively studied form of LTD, involves the endocytosis of AMPA receptors (AMPARs) via protein dephosphorylation, but the underlying mechanism has remained unclear," scientists writing in the journal Plos Biology report (see also Endocytosis).
"We show here that a regulated interaction of the endocytic adaptor RalBP1 with two synaptic proteins, the small GTPase RalA and the postsynaptic scaffolding protein PSD-95, controls NMDAR-dependent AMPAR endocytosis during LTD. NMDAR activation stimulates RalA, which binds and ...
