A comprehensive web resource on RNA helicases from the baker's yeast Saccharomyces cerevisiae.

Members of the RNA helicase protein family are defined by several motifs that have been widely conserved during evolution. They are found in all organisms-from bacteria to humans-and many viruses. The minimum number of RNA helicases present within a eukaryotic cell can be predicted from the complete sequence of the Saccharomyces cerevisiae genome. Recent progress in the functional analysis of various family members has confirmed the significance of RNA helicases for most cellular RNA metabolic processes. We have assembled a web resource that focuses on RNA helicases from the budding yeast Saccharomyces cerevisiae. It includes descriptions of RNA helicases and their functions, links to sequence- and yeast-specific databases, an extensive list of references, and links to non-yeast helicase web resources.
