Answer:
A mutation in the N-terminal region may alter protein stability  
Explanation:
Transport proteins are proteins capable of transporting substances through biological membranes. These proteins are located within cellular membranes where they form channels that allow the movement of substances between the internal and external sides of the membrane. The N-terminus is the first region in the protein that emerges from the ribosome during its synthesis. This region is usually composed of signal peptides consisting of about 30 amino acids required for protein delivery. Moreover, the N-terminal region is also important because it dictates protein degradation by peptidases. Consequently, mutations in the N-terminal region of transport proteins can alter the properties of these proteins, i.e., either by modifying protein stability or by altering protein signaling.
