Abstract
This invention relates to compositions and methods for modulating cellular activity of non-human organisms, and in particular fungi, and methods of identifying and using antifungal agents with improved specificity. More particularly, the technology described herein relates to the identification and use of compounds that target intron-encoded proteins, such as maturases.
Claims15
A method for screening an agent for modulating cellular activity of a non-human organism, wherein said organism contains an intron comprising a nucleic acid encoding a protein that effects IREP-mediated post-transcriptional processing of RNA, said method comprising the steps of:
- a) providing the protein in an assay format adapted for studying the effects of the protein on post-transcriptional processing of pre-mRNA;
- and
- b) assaying for said effects in the presence of the agent.
A method for screening an agent for modulating IREP-mediated post-transcriptional processing of RNA, said method comprising the steps of:
- a) preparing a nucleic acid construct comprising an open reading frame encoded by the IREP and a reporter gene functionally associated therewith:
- b) expressing protein from the nucleic acid construct;
- and
- c) detecting translation of the reporter gene, wherein a change in translation in the presence of the agent indicates modulation of the IREP-mediated post-transcriptional processing of RNA.
A method for modulating cellular activity of a non-human organism associated with a host organism, wherein said non-human organism belongs to a taxonomic group, said method comprising the steps of:
- a) identifying an IREP specific for the taxononic group;
- b) identifying an agent that modulating IREP-mediated post-transcriptional processing of RNA;
- and
- c) administering an effective amount of the agent to the host organism.
A pharmaceutical composition for inhibiting growth of a non-human organism associated with a host organism, wherein said non-human organism belongs to a taxonomic group of organisms, said compositions comprising:
- an agent that modulates IREP-mediated post-transcriptional processing of RNA, wherein said IREP is specific for the taxonomic group;
- and a pharmaceutically acceptable carrier.
