Reacts with the 130 kDa integrin β1 subunit, CD29, that is expressed following cell activation as a heterodimeric complex with one of nine
distinct α subunits, comprising the very late activation antigen (VLA) subfamily of adhesion receptors. The HUTS-21 β1 epitope is weakly
expressed on resting lymphocytes, but is upregulated by TPA, Ca++ ionophore, or another CD29 antibody, TS2/16. This upregulation is
Mn++ dependent and not supported by other divalent cations such as Ca++ and/or Mg++. The VLA receptors have a broad cellular
distribution and interact with ligands like VCAm-1 and MAdCAM-1 during cell adhesion. They also interact with extra-cellular matrices
including collagen, laminin, fibronectin and others. HUTS-21 antibody enhances adherence of TPA-activated lymphocytes to fibronectin.
