    摘要: This invention provides a method of modulating translation termination efficiency of mRNA and/or promoting degradation of abberant transcripts. Also, this invention provides a method of screening for a drug active involved in enhancing translation termination and a method for identifying a disease state involving defective the protein complex. This invention provides a purified complex comprising an amount of a human Upf1p protein, a peptidyl eucaryotic release factor 1 (eRF1) and a peptidyl eucaryotic release factor 3 (eRF3) effective to modulate translation termination. Further, this invention provides an expression vector which comprises a nucleic acid encoding a human Upf1p protein, a peptidyl eucaryotic release factor 1 (eRF1) and a peptidyl eucaryotic release factor 3 (eRF3) operably linked to a regulatory element. This invention provides an antibody which binds to the complex comprising an amount of a human Upf1p protein, a peptidyl eucaryotic release factor 1 (eRF1) and a peptidyl eucaryotic release factor 3 (eRF3) effective to modulate translation termination. This invention provides an agent which inhibits or modulates the binding of human Upf1p to eRF1 or eRF3 The agent may inhibit or facilitate the binding of human Upf1p to eRF1 or eRF3.

    摘要: A method of identifying an antiviral agent effective against viruses, which utilize −1 programmed ribosomal frameshifting is provided. The method includes providing cells harboring a −1 frame plasmid including a translation start site followed by a −1 ribosomal frameshifting signal followed by a reporter gene which is in a −1 frame relative to the translation start site. The method further includes contacting the cells with a test agent; and measuring the activity of the reporter gene in the presence of the test agent, wherein the reporter gene activity is dependent on −1 ribosomal frameshifting.
