p80 ROKalpha binding protein is a novel splice variant of CRMP-1 which associates with CRMP-2 and modulates RhoA-induced neuronal morphology.

abstract：:In the filamentous fungus Neurospora, the production of dsRNA can elicit a dsRNA-induced transcriptional response similar to the interferon response in vertebrates. However, how fungi sense the expression of dsRNA and activate gene expression is unknown. In this study, we established a dsRNA response reporter system i...
