What does IRESS mean in UNCLASSIFIED
Internal Ribosome Entry Sites (IRES) segments are important non-coding regions of various RNA molecules that allow for higher levels of protein production in a cell. IRES segments are found within messenger RNAs, transfer RNAs and ribosomal RNAs. When the cell needs to produce more proteins, it will recognize these specific sequences, binding them to its internal ribosomes and allowing for higher levels of expression of coding genetic material than would normally be possible.

Essential Questions and Answers on Internal ribosome entry sites segments in "MISCELLANEOUS»UNFILED"
What are Internal Ribosome Entry Sites (IRESS)?
Internal ribosome entry sites (IRESS) are RNA transcripts that enable a type of regulation in the post-transcriptional stage of gene expression. They act as a bridge between mRNA and the ribosomes, allowing for proteins to be synthesized more efficiently.
How does IRESS work?
IRESS acts as an ‘on switch' which allows ribosomes to dock onto mRNAs when activated by a specific protein, which in turn starts the process of translation - the conversion of mRNA into proteins.
What type of gene expression does IRESS regulate?
IRESS regulates post-transcriptional gene expression, meaning it enables regulation on mRNA transcripts after they have been transcribed from DNA.
How do IRESS segments interact with other molecules?
IRESS segments interact with various molecules such as polypeptide elongation factor 1 and initiation factors to form a bridge between mRNA and ribosomes. The binding of these molecules triggers the start of protein synthesis.
Are there any advantages associated with using IRESS?
Yes, one advantage is that using this system improves the speed at which proteins can be made since it bypasses certain transcription steps, and also reduces cellular energy expenditure since fewer transcription steps are needed.
Is there any evidence that suggests animals use IRESS?
Yes, some research has shown evidence that animals such as mice and humans express genes through internal ribosome entry sites (IRES), though it is unclear what proportion of genes utilize this method.
Can viruses make use of Internal Ribosome Entry Sites (IRES)?
Yes, some viruses have been found to contain sequences similar to those found in mRNAs that possess internal ribosome entry sites (IRES). This suggests that certain viruses may be able to employ this system for the production of their viral proteins.
Are there any possible side effects associated with using IRES?
While there is no direct evidence demonstrating side effects related specifically to using internal ribosome entry sites (IRES), increased levels of gene expression can lead to an increase in cell stress levels and reduced control over protein synthesis.
Does genetic engineering rely on Internal Ribosome Entry Site technology?
Yes, the manipulation of genes often requires efficient methods for protein production - something which internal ribosome entry site technology can help facilitate due to its ability to rapidly initiate translation.
Is it possible for multiple proteins to be produced from a single IRES segment?
Yes, several studies have demonstrated that multiple distinct proteins can be produced from a single upstream open reading frame if different start codons are present within the transcript.
Final Words:
In conclusion, IRES segments are short nucleotide sequences on RNA molecules which allow for increased rates of gene expression via their ability to bind with cellular ribosomes and initiate protein synthesis at a faster rate than normal expression mechanisms could provide alone. These often overlooked segments play crucial roles in determining how much and how rapidly certain proteins within cells can be produced in response to various environmental signals.
