Vascular cell adhesion molecule 1 (VCAM-1) represents a structurally and, functionally distinct class of immunoglobulin superfamily molecules that, bind leukocyte integrins and are involved in inflammatory and immune, functions. X-ray crystallography defines the three-dimensional structure, of the N-terminal two-domain fragment that participates in ligand binding., Residues in domain 1 important for ligand binding reside in the C-D loop, which projects markedly from one face of the molecule near the contact, between domains 1 and 2. A cyclic peptide that mimics this loop inhibits, binding of alpha 4 beta 1 integrin-bearing cells to VCAM-1. These data, demonstrate how crystallographic structural information can be used to, design a small molecule inhibitor of biological function.

== Function ==

[https://www.uniprot.org/uniprot/VCAM1_HUMAN VCAM1_HUMAN] Important in cell-cell recognition. Appears to function in leukocyte-endothelial cell adhesion. Interacts with the beta-1 integrin VLA4 on leukocytes, and mediates both adhesion and signal transduction. The VCAM1/VLA4 interaction may play a pathophysiologic role both in immune responses and in leukocyte emigration to sites of inflammation.

Vascular cell adhesion molecule 1 (VCAM-1) represents a structurally and functionally distinct class of immunoglobulin superfamily molecules that bind leukocyte integrins and are involved in inflammatory and immune functions. X-ray crystallography defines the three-dimensional structure of the N-terminal two-domain fragment that participates in ligand binding. Residues in domain 1 important for ligand binding reside in the C-D loop, which projects markedly from one face of the molecule near the contact between domains 1 and 2. A cyclic peptide that mimics this loop inhibits binding of alpha 4 beta 1 integrin-bearing cells to VCAM-1. These data demonstrate how crystallographic structural information can be used to design a small molecule inhibitor of biological function.
