What type of simple-pass membrane protein would contain a hydrophobic membrane-spanning α-helix?
A)transmembrane protein
B)integral membrane protein
C)peripheral protein
D)transmembrane protein and integral membrane protein

Question

Quizplus · Accepted Answer

Transmembrane proteins and integral membrane proteins both span the entire lipid bilayer and have hydrophobic regions that interact with the hydrophobic core of the membrane. Therefore, if a simple-pass membrane protein contains a hydrophobic membrane-spanning α-helix, it would be classified as both a transmembrane and integral membrane protein.
