The integrin alpha 4 (also known as CD49d and ITGA4) belongs to the integrin alpha chain family of proteins.
Integrins are heterodimeric integral membrane proteins composed of an alpha and beta chains.
Alpha 4 chain associates with either beta 1 or beta 7 chain.
It has been demonstrated that the putative ligand-binding sites of both integrin alpha 4 beta 1 and alpha 4 beta 7 is located on the alpha 4 chain.
These ligands included Madcam, VCAM, and fibronectin.
Madcam is known as the principal ligand for integrin alpha 4 beta 7.
Recently it was also demonstrated that HIV-1 envelope can mimic Madcam by binding to and signaling though integrin alpha 4 beta 7, the gut mucosal homing receptor for peripheral T cells.
Despite its predicted molecular weight, Integrin alpha 4 will often run at higher molecular weight in SDS-PAGE.
At least two isoforms are known to exist.
The immunogen to this antibody is outside of the Integrin alpha 4 recombinant protein fragment and thus will not recognize it.
Applications:Suitable for use in Western Blot.
Other applications not tested.
Recommended Dilution:Western Blot: 0.5-1ug/mlOptimal dilutions to be determined by the researcher.
