Members of the RNA helicase protein family are defined by several motifs th
at have been widely conserved during evolution. They are found in all organ
isms-from bacteria to humans-and many viruses. The minimum number of RNA he
licases present within a eukaryotic cell can be predicted from the complete
sequence of the Saccharomyces cerevisiae genome. Recent progress in the fu
nctional analysis of various family members has confirmed the significance
of RNA helicases for most cellular RNA metabolic processes. We have assembl
ed a web resource that focuses on RNA helicases from the budding yeast Sacc
haromyces cerevisiae. It includes descriptions of RNA helicases and their f
unctions, links to sequence- and yeast-specific databases, an extensive lis
t of references, and links to non-yeast helicase web resources. Copyright (
