Western blot - Anti-Integrin alpha 4/CD49D antibody [EPR1355Y] - BSA and Azide free (AB239898)

This data was developed using ab81280, the same antibody clone in a different buffer formulation.

Lanes 1 - 2 : Merged signal (red and green). Green - ab81280 observed at 150 kDa. Red - loading control, ab8245, observed at 37 kDa.

This blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using Licor blocking buffer before being incubated with ab81280 and ab8245 (loading control) overnight at 4°C. Antibody binding was detected using Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preabsorbed (ab216776) at a 1 : 10000 dilution for 1hr at room temperature and then imaged.

Western blot - Anti-Integrin alpha 4/CD49D antibody [EPR1355Y] - BSA and Azide free (AB239898)

This data was developed using ab81280, the same antibody clone in a different buffer formulation.

Lane 1 : Integrin alpha 4 knockout HAP1 cell lysate (20 μg)

Lane 2 : Wild-type HAP1 cell lysate (20 μg)

Lanes 1 and 2 : Merged signal (red and green). Green - ab81280 observed at 150 kDa. Red - loading control, ab8226, observed at 42 kDa.

ab81280 was shown to recognize Integrin alpha 4 in wild-type HAP1 cells along with additional cross-reactive bands. No bands were observed when Integrin alpha 4 knockout samples were used. Wild-type and Integrin alpha 4 knockout samples were subjected to SDS-PAGE. ab81280 and ab8226 (loading control to beta actin) were diluted 1/2000 and 1/1000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10,000 dilution for 1hr at room temperature before imaging.

Supplementary information

Integrin alpha 4 also known as CD49D or ITGA4 is a transmembrane receptor with a mass of approximately 150 kDa. This protein is expressed on the surface of leukocytes including T and B lymphocytes monocytes and eosinophils. Integrin alpha 4 functions by interacting mechanically with the extracellular matrix components and endothelial cell counter-receptors like VCAM-1 facilitating cell adhesion and migration. Its expression is vital for the immune cells' ability to move and locate sites of inflammation or injury.

Biological function summary

Integrin alpha 4 forms a heterodimer complex with beta subunits like beta 1 (forming VLA-4) or beta 7 allowing it to mediate adhesion and signaling pathways. In particular the alpha 4 and beta 1 dimerization gives rise to a high-affinity receptor for fibronectin and VCAM-1. This interaction is essential for regulating immune responses and maintaining cell positioning within tissues. The presence of this complex on leukocytes drives their ability to navigate through the vasculature to inflamed areas.

Pathways

Integrin alpha 4 participates in significant signal transduction pathways including the MAPK and PI3K-Akt pathways. These pathways modulate cell survival proliferation and migration. In the MAPK pathway integrin alpha 4 influences cell signaling cascades by interacting with other proteins like TALIN or PAXILLIN which are important for integrin-mediated signal relay. In connection with PI3K-Akt pathway alpha 4 integrins work closely with proteins in regulating cellular adhesion and motility showing a dynamic interplay in immune regulation.

Integrin alpha 4 plays an important role in various immune-related diseases such as multiple sclerosis and Crohn's disease. The protein's participation in leukocyte adhesion and trafficking makes it a target for therapeutic intervention. Natalizumab a monoclonal antibody against alpha 4 integrin showcases the critical link between the protein and disease treatment by blocking leukocyte migration to reduce inflammation. Additionally integrin alpha 4's interaction with proteins like VCAM-1 and VLA-4 highlights its relevance in these autoimmune conditions highlighting its importance in disease pathophysiology.

Target data

Integrins alpha-4/beta-1 (VLA-4) and alpha-4/beta-7 are receptors for fibronectin. They recognize one or more domains within the alternatively spliced CS-1 and CS-5 regions of fibronectin. They are also receptors for VCAM1. Integrin alpha-4/beta-1 recognizes the sequence Q-I-D-S in VCAM1. Integrin alpha-4/beta-7 is also a receptor for MADCAM1. It recognizes the sequence L-D-T in MADCAM1. On activated endothelial cells integrin VLA-4 triggers homotypic aggregation for most VLA-4-positive leukocyte cell lines. It may also participate in cytolytic T-cell interactions with target cells. ITGA4 : ITGB1 binds to fractalkine (CX3CL1) and may act as its coreceptor in CX3CR1-dependent fractalkine signaling (PubMed : 23125415). ITGA4 : ITGB1 binds to PLA2G2A via a site (site 2) which is distinct from the classical ligand-binding site (site 1) and this induces integrin conformational changes and enhanced ligand binding to site 1 (PubMed : 18635536, PubMed : 25398877). Integrin ITGA4 : ITGB1 represses PRKCA-mediated L-type voltage-gated channel Ca(2+) influx and ROCK-mediated calcium sensitivity in vascular smooth muscle cells via its interaction with SVEP1, thereby inhibiting vasocontraction (PubMed : 35802072).
