Description
Goal
- Describe the relationship between structure and function in proteins and the implications of changes in structure on the operation of a cell.

We recently learned about transcription and making copies of messenger RNA (mRNA). These mRNA copies can make a number of proteins with a wide range of functions. In fact, the human body contains somewhere between 50,000 & 200,000 proteins which make up almost 50% of the dry weight of a typical cell! Many researchers are actively trying to determine the function for undescribed proteins identified from DNA. For this week’s discussion, I want you to use the library or web to find an described cellular protein (i.e. one that has a function already determined) that you will briefly introduce to the class. This cellular protein can be described in humans, any other living organism, or even viruses! For this week’s discussion answer the following:
- What is the name of your protein?
- Where can the protein be found in the cell (where in or on the cell or outside of the cell if it is extracellular)?
- What is the function of your protein?
- What might a mutation possibly do for this protein (e.g., will it be better adapted to its environment, could the protein be non-functional)?
- By Sunday: Please make an initial reply to this post. For your initial post, I am looking for well supported reply (please provide more than three sentence replies!). Feel free to link studies or trustworthy articles that support your post. Please use complete sentences and appropriate grammar.
