Все это указывает на то, что Eph рецепторы участвуют в синаптической пластичности. Фосфорилирование NMDA рецепторов нуждается в экспресии EphB2 рецепторов полной длины. EphB2, у которых отсутствует внутриклеточный домен, достаточны для устранения эффект а нокаута на синаптическую пластичность.

(Рис.1.) | CaMKII in the postsynaptic density is ideally positioned to detect local Ca2+ entry through the NMDA receptor. (Рис.2.) | Structure and regulation of CaMKII. (Рис.3.) | Different forms of CaMKII activation. (Рис.4.) | CaMKII and its substrate GluR1 are phosphorylated after hippocampal LTP and dephosphorylated after depotentiation. (Рис.5.) | LTP induced by a pairing protocol requires CaMKII activity. (Рис.6.) | Effects of perfusion of active CaMKII on CA1 pyramidal cells. (Рис.7.) | Multiple mechanisms by which CaMKII might enhance transmission. (Рис.8.) | CaMKII activity promotes synaptic maturation in vivo. (Рис.9.) | CaMKII affects cortical plasticity. (Рис.10.) | Learning and memory are affected in animals that express a mutant form of CaMKII. |
