STRUCTURE OF THE RNAI POLYMERASE FROM NEUROSPORA CRASSA
Overview
RNA silencing refers to a group of RNA-induced gene-silencing mechanisms, that developed early in the eukaryotic lineage, probably for defence, against pathogens and regulation of gene expression. In plants, protozoa, fungi, and nematodes, but apparently not insects and vertebrates, it, involves a cell-encoded RNA-dependent RNA polymerase (cRdRP) that produces, double-stranded RNA triggers from aberrant single-stranded RNA. We report, the 2.3-A resolution crystal structure of QDE-1, a cRdRP from Neurospora, crassa, and find that it forms a relatively compact dimeric molecule, each, subunit of which comprises several domains with, at its core, a catalytic, apparatus and protein fold strikingly similar to the catalytic core of the, DNA-dependent RNA polymerases responsible for ...
