Suppose There Is a Mutation in a Laminin-Binding Integrin Gene

question 122

Multiple Choice

Suppose there is a mutation in a laminin-binding integrin gene that causes a loss of function in the cytoplasmic domains of the integrin. Which one of the following would you expect to observe as a result of this mutation?

• A)The strength of tissues would be decreased because the integrin could no longer associate with intermediate filaments in hemidesmosomes.
• B)The integrin would function normally because the cytoplasmic domain is not responsible for binding to laminin.
• C)Cell adhesion to laminin would decrease, but laminin-meditated gene expression would remain the same.
