Chapter 5, Problem 2IQ
Summary Introduction
To describe: The way in which one would recognize an integral membrane protein based only on the amino acid sequence.
Introduction: A cell membrane is also called a cytoplasmic membrane or plasma membrane. A transmembrane protein is a type of integral membrane protein. It spans the entirety of the cell membrane. The cell membranes consist of a variety of different transmembrane proteins.
