A cancer drug is being tested, and it is found that although the cancer cells can divide, the nuclear envelope cannot re-form. It is determined that a protein substance is sequestered so that it cannot be polymerized into the necessary structure. What is the most likely protein target of the drug?

A. β-tubulin

B. α-tubulin

C. Lamin

D. Keratin

E. Actin

Paige · Answer 1

C. Lamin

Explanation:

Lamin is one of the most important proteins that form the nuclear envelope. These fibrous proteins are mostly present in the inner nuclear membrane and have a structural function in the cell.

If this protein is targeted, the nuclear envelope will not be able to reform, which would lead to the death of the cell.
