Distinct activities of the DExD/H-box splicing factor hUAP56 facilitate stepwise assembly of the spliceosome.

abstract：:Neuronal depolarization and CaM kinase IV signaling alter the splicing of multiple exons in transcripts for ion channels, neurotransmitter receptors, and other synaptic proteins. These splicing changes are mediated in part by special CaM kinase-responsive RNA elements, within or adjacent to exons that are repressed in...
