Research Abstract |
netrin-G1 and netrin-G2 are expressed on axons of distinct neuronal circuits and form functionally distinct subdomains on dendrites via interaction with their specific ligands, NGL-1 and NGL-2, at synapses. Electrophysiologic and behavioral studies on mice lacking either netrin-G1 or netrin-G2 revealed that netrin-G/NGL interaction had important roles for maintaining the integrity of synaptic function and plasticity. Moreover, we provided evidence that the differential expression patterns of duplicated netrin-G1 and netrin-G2 genes were acquired by "special subfunction partitioning".
