. What are the main transcription factors which are downstream of LAT?
Homework Answers
Elf-1 is the main transcription factor for the regulation of LAT gene. The LAT gene codes an adaptor protein (intracellular) that connects the cell surface receptor linkage to the numerous signaling events downstream. It plays an integral role in the cell type functions that express the gene that includes the mast, natural killer and T cells, and the platelets. The Elf-1 expression is very high in the T-cells that include GMCSF cells, interleukin-2 receptor alpha unit and the TCR zeta chain.

What is the role of the transcription factors? A mutation exists in transcription factors that causes them to bind slightly downstream of the TATA box, causing them to cover the first 3 nucleotides of a gene. RNA polymerase can still transcribe the gene to mRNA, but it misses the first 3 nucleotides. How would this impact translation?

What is the role of the transcription factors? A mutation exists in transcription factors that causes them to bind slightly downstream of the TATA box, causing them to cover the first 3 nucleotides of a gene. RNA polymerase can still transcribe the gene to mRNA, but it misses the first 3 nucleotides. How would this impact translation? RNA is single stranded, and as such, undergoes rapid rates of mutation. How would this affect the ability of siRNAs to combat RNA...

Classify each statement according to whether it applies to general transcription factors only, specific transcription factors only, both, or neither These transcription factors are found in both prokaryotes and eukaryotes. These transcription factors are proteins. These transcription factors form part of the transcription complex. One of these transcription factors binds directly to the TATA box in the core promoter. These transcription factors bind to the operator. These transcription factors bind to enhancer sequences that may be distant from the promoter....

Last week we discussed the role of general transcription factors in forming the transcription initiation complex in eukaryotes. Next week we will look more closely at the regulation of gene expression and the role played by specific transcription factors. Prokaryotes and eukaryotes utilize very different mechanisms for determining which genes are turned on and off and when. In lieu of the prokaryotic operon model, eukaryotes employ a combinatorics approach utilizing both general and specific transcription factors. For this week’s forum,...
