Integrin alpha 4 beta 1: Proteins and Enzymes

Integrin alpha 4 beta 1, also known as VLA-4, is an Integrin family adhesion receptor that shares the beta 1 subunit with eleven other family members and the alpha 4 subunit with Integrin alpha 4 beta 7. The noncovalent heterodimer of alpha 4/CD49d and beta 1/CD29 subunits mediates cell adhesion to VCAM-1/CD106 on other cells and the CS-1 fragment of Fibronectin in the extracellular matrix. Leukocytes (except for neutrophils), erythroid precursors, and some non-hematopoietic cells such as ...
