Extracellular domain of type I receptor for transforming growth factor-beta: molecular modelling using protectin (CD59) as a template.

abstract：:Two RNA silencing-related phenomena, quelling and meiotic silencing by unpaired DNA (MSUD) have been identified in the fungus Neurospora crassa. Similar to the case with the siRNA and miRNA pathways in Drosophila, different sets of protein components including RNA-dependent RNA polymerase, argonaute and dicer, are use...
