Integrin α3β1 (VLA-3 or CD49c, UniProtKB P26006) belongs to the family of integrins, heterodimeric cell surface receptors that play a pivotal role in cell adhesion, migration, growth and survival. The integrin family contains 18 α- and 8 β-subunits that can form 24 different integrin heterodimers that bind different ligands. Via cooperation with other types of cell surface receptors (e.g. growth factor or G-protein coupled receptors), integrins can regulate intracellular signaling. Integrin beta-1 is the most abundant β-integrin forms dimers with at least 10 different alpha subunits to form for example the Very Late Antigens VLA-3 (α3β1 integrin) or VLA-4 (α4β1 integrin). VLA-3 functions as a receptor for collagen, laminin, and fibronectin and overexpressed in various types of cancer.
