Interactions between growing axons and synaptic basal lamina components direct the
formation of neuromuscular junctions during nerve regeneration. Isoforms of laminin
containing α5 or β2 chains are potential basal lamina ligands for these interactions. The
nerve terminal receptors are unknown. Here we show that SV2, a synaptic vesicle
transmembrane proteoglycan, is complexed with a 900-kDa laminin on synaptosomes from
the electric organ synapse that is similar to the neuromuscular junctions. Although two …
