Definition
An integral membrane protein (also called IMP) is a protein molecule permanently attached to a biological membrane (such as a cell membrane or the membrane of an organelle in a eukaryotic cell).
Types
Integral membrane proteins are of two main types:
- transmembrane protein (also called integral polytopic protein)
- integral monotopic protein
