Formation of the neuromuscular junction requires the release of agrin from the presynaptic terminal of motor neurons. Clustering of acetylcholine receptors (AChRs) on the postsynaptic sarcolemma is initiated by agrin-dependent activation of the muscle-specific kinase. While the postsynaptic scaffolding protein rapsyn is vital for high density AChR(More)
Heterogeneous ribonucleoprotein (hnRNP) A2 is a trans-acting factor that mediates intracellular trafficking of specific RNAs containing the A2 response element. HnRNP A2 is localized in the nucleus and also in granules in the perikaryon and processes in oligodendrocytes. The distribution of the cytoplasmic pool of hnRNP A2 is microtubule-dependent. HnRNP A2(More)
Clustering of acetylcholine receptors at the developing vertebrate neuromuscular junction is initiated by neural agrin, which stimulates the activity of the muscle-specific kinase (MuSK). Acetylcholine receptor clustering is also dependent on the postsynaptic scaffolding protein, rapsyn, which binds to acetylcholine receptors. Here, we address the(More)
PURPOSE X-linked juvenile retinoschisis (XLRS) is a vitreoretinal dystrophy characterized by schisis (splitting) of the inner layers of the neuroretina. Mutations within the retinoschisis (RS1) gene are responsible for this disease. The mutation spectrum consists of amino acid substitutions, splice site variations, small indels, and larger genomic(More)
