orphan date June 2010 A nonsense suppressor is a tRNA mutation that suppresses the protein truncation resulting from a nonsense mutation . The nonsense suppressor is a tRNA gene from Escherichia coli which has an Transfer RNA Anticodon anticodon mutated to recognize the nonsense stop Genetic code codon . As a result, when the ribosome reaches the codon in question, the nonsense suppressor will sometimes bind and incorporate its amino acid instead of the regular stop codon tRNA binding and causing termination , allowing translation to continue. The frequency of this event is the ratio of the nonsense suppressor expression to the expression of the correct tRNA for that stop codon. This is a useful genetic tool, but can also result in problematic side effects, since all identical stop codons in the genome will also be suppressed to the same degree. Genes with different or multiple stop codons will be unaffected. SUP35, a nonsense suppressor identified by Reed Wickner Wickner in 1994, is a Prion prion protein .

Refimprove date May 2007 A suppressor grid is a grid used in a thermionic valve also called vacuum tube to suppress secondary emission . A suppressor grid is also called the antidynatron grid, as it helps to reduce the dynatron effect. Placement In its simplest form, a suppressor grid, typically of coarse structure, is interposed between the screen grid and the anode Plate electrode plate of a tetrode , turning it into a pentode . Electrical connection of grid The suppressor grid is usually connected to the cathode and more often than not, this connection is made within the glass envelope. Because the grid is negatively charged relative to both the anode and the screen grid, it repels any secondary electrons back to the anode preventing them from contributing to the screen grid current, and to any negative resistance characteristic.

An echo suppressor sometimes acoustic echo suppressor AES is a telecommunications device used to reduce the Echo phenomenon echo heard on long telephone Telecommunication circuit circuits , particularly circuits that traverse satellite links. Echo suppressors were first developed in the 1950s in response to the first use of satellites for telecommunications, but they have since been largely supplanted by better performing echo canceller s. Operation Echo suppressors work by detecting if there is a voice signal going in one direction on a circuit, and then inserting a great deal of loss in the other direction. Usually the echo suppressor at the far end of the circuit adds this loss when it detects voice coming from the near end of the circuit. This added loss prevents the speaker from hearing his own voice. Limitations While effective, this approach leads to several problems Double talk It is fairly normal in conversation for both parties to speak at the same time, at least briefly. Because each echo suppressor will then detect voice energy coming from the far end of the circuit, the effect would ordinarily be for loss to be inserted in both directions at once, effectively blocking both parties. To prevent this, echo suppressors can be set to detect voice activity from the near end speaker and to fail to insert loss or insert a smaller loss when both the near end speaker and far end speaker are talking. This, of course, temporarily defeats the primary effect of having an echo suppressor at all. Clipping Since the echo suppressor is alternately inserting and removing loss, there is frequently a small delay when a new speaker begins talking that results in clipping the first syllable from that speaker s speech. Dead set If the far end party on a call is in a noisy environment, the near end speaker will hear that background noise while the far end speaker is talking, but the echo suppressor will suppress this background noise when the near end speaker starts talking. The sudden ... more details

Such abnormal proteins are produced due to mutation of the concerned gene .

Examples of tumor specific antigens include the abnormal products of ras and p53 genes.
