Genetics Protein?

Question

In eukaryotes, it is not uncommon for a single effector protein to regualte the synthesis of several different proteins encoded by distinct RNAs. Explain in molecular terms how this could happen?

Answer 1

That effector molecule you are referring to often will be a transcription factor. One very famous example is NF-kB. Every gene has elements in their promoter region that regulate the transcription of that gene. These transcription factors will be able to bind their specific elements in the promoter and initate transcription of that gene. So several genes can have promoter elements for NF-kB, therefore, when NF-kB is made, it will initiation transcription of several genes, leading to translation of the genes, and then proteins.
