You are working on a research project involving a novel transcription factor that regulates gene expression specifically in muscle cells (called MUSC1). You have already done an experiment where you showed that the addition of MUSC1 to muscle cells in culture greatly increased the expression of both actin and myosin (contractile proteins in muscle cells). Answer the following questions below:

Is MUSC1 a general or regulatory transcription factor? Explain your answer.

What two specific components would you expect MUSC1 to have as part of its protein structure?


Briefly describe the two main ways in which MUSC1 could act to stimulate transcription of actin and myosin


Describe an experiment that you could perform to demonstrate that MUSC1 binds to the promoter/enhancer region of actin and myosin genes.


A potential nuclear localization signal has been identified within the protein sequence of the transcription factor MUSC1. What experiments would you perform to demonstrate that this sequence is both necessary and sufficient for nuclear localization?


MUSC1’s entry into the nucleus is regulated so that it only goes into the nucleus to regulate the expression of contractile proteins at the correct time. Describe one mechanism by which this type of regulation can occur in the cell.

The clinical symptoms of two forms of galactosemia show radically different severity.

  1. Deficiency of galactokinase
  2. Deficiency of UDP-glucose:galactose 1-phosphate uridylyltransferase

Although both types produce gastric discomfort after milk ingestion, deficiency of the transferase also leads to liver, kidney, spleen, and brain dysfunction and eventual death.

Explain, what products accumulate in the blood and tissues with each type of enzyme deficiency? (3 point)

List the symptoms for each type of deficiency. (3 point).

Explain which of these products is more toxic and why?
