Extra cellular adherence protein

Cell adhesion proteins, also known as cell adhesion molecules, are molecules involved in the interaction between cells and cells and between cells and extracellular matrices. Cell adhesion refers to adhesion between cells, which is a form of information exchange between cells. The soluble transmitter of information exchange is called cell adhesion molecule (CAM). CAM is a class of independent molecular structure, which makes cells adhere to each other by recognizing its specific receptor.
Cell adhesion protein is a transmembrane glycoprotein, and its molecular structure consists of three parts: 1. extracellular domain, N-terminal part of peptide chain, with sugar chain, responsible for ligand recognition; 2. transmembrane region, mostly once Transmembrane; 3. cytoplasmic region, the C-terminal portion of the peptide chain, generally smaller, or directly linked to the framework component under the plasma membrane, or linked to intracellular chemical signaling molecules to activate the signal transduction pathway.
