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)
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)
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)
Transfection of cells in culture with cDNA constructs is a powerful tool in cell biology, but postmitotic cells, including myotubes, can be hard to transfect with classic methods. Biolistics provides an alternative. We have used this biolistic technique to introduce cDNAs into cultured rat, chick, and C2C12 myotubes. This protocol results in efficient (20(More)
