What is the biochemical outcome of Zellweger's (disease) mutated protein?

What is the biological consequence of the mutation?

How does the mutation lead to a defective biochemical pathway that leads to the phenotype?

Does the mutations affect the promoter? If so, explain

Expert Solution

# Zellweger's disease is characterised by reduction or absence of functional peroxisomes in the cells.

# Yes, it is an outcome of mutation in the genes that encode peroxins, a protein assembles the normal peroxisomes. Mutation in PEX1, PEX2 and other PEX genes causes this disease.

# This mutation causes impaired brain development, hypomyelination, hepatomegaly and hypotonia.

# As a result of impaired function of peroxisomes, very long chain and branched chain fatty acids accumulate in the cells or tissues of the patients which would normally be degraded in normal peroxisomes. Accumulation of these fatty acids impair the normal function of the multiple organs.

Imagine that Arf1 protein was mutated so that it could not hydrolyze GTP, regardless of its binding partners. Would you expect COPI-coated vesicles to form normally? How would you expect transport mediated by COPI-coated vesicles to be affected? If this were the only form of Arf1 in a cell, would you expect it to be lethal? Briefly explain your answers.

Cystic fibrosis is genetic disease caused by mutations in the CFTR gene. The consequence of this is production of an abnormal transmembrane protein that is responsible for producing sweat, mucus, and digestive fluids. Explain in depth the correlation between the defective gene and the abnormal protein that is produced. Be sure to mention the process involved in protein production, whether or not those process(s) have occurred, and their end products. Provide details in your explanation and support your answer with...
