Integrin ??2??1 is a heterodimeric adhesive protein receptor belonging to the ??1 subfamily. It serves as a collagen receptor on fibroblasts and platelets and additionally as a laminin receptor on epithelial and endothelial cells
Collagen signaling nduces NF-??B Activity in fibroblasts probably via this receptor.

Treatment with ??v??5 blocking antibody reduces integrin ??1/matrix binding.
increase in ??5 cell-surface levels after uPA-silencing promotes ??1-mediated cell attachment that correlates with a decrease in integrin ??1 activity.

In the endoplasmic reticulum, integrin subunits find their binding partners and form heterodimers.
Monomeric integrins never reach the cell surface.

During gastrulation, type 1 EMT is associated with de novo expression of a5b1, which is a receptor for fibronectin.
Type 2 EMT in experimental kidney fibrosis is associated with increased a5 integrin expression.

L1 also interacts heterophilically with laminin in the context of mouse small cerebellar neurons
Integrins (b1, a3, a6) could be shown to bind to laminin by a b1-dependent adhesion mechanism.
L1 was demonstrated to bind in a concentration-dependent and saturating manner to laminin.
Furthermore, antibodies to the Ig-like domains of L1 and b1 integrin inhibited partially cell adhesion to laminin.
