Summary Introduction
To explain: The pattern of Siamese cat’s fur pigmentation due to ‘temperature-sensitive’ mutation in the gene encoding dark fur pigment.
Concept introduction:
Siamese cats have unique fur pigmentation pattern known as ‘colorpoints’. The pattern includes dark ears, face, legs, and tail, while a creamy white shade is seen on the back and belly. They are partial albinos. This is caused due to a ‘temperature-sensitive’ mutation in the gene encoding tyrosinase enzyme required for the melanin production. It does not work at normal body temperatures.

Molecular Biology Question
You are working to characterize a novel protein in mice. Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas. However, an antibody that recognizes the C-terminal portion of the protein indicates that the protein is present in brain, muscle, and liver, but not in the pancreas. What is the most likely explanation for this result?
