Function
Integrin alpha-6/beta-4 is a receptor for laminin. Plays a critical structural role in the hemidesmosome of epithelial cells. Is required for the regulation of keratinocyte polarity and motility. ITGA6:ITGB4 binds to NRG1 (via EGF domain) and this binding is essential for NRG1-ERBB signaling (PubMed:20682778). ITGA6:ITGB4 binds to IGF1 and this binding is essential for IGF1 signaling (PubMed:22351760). ITGA6:ITGB4 binds to IGF2 and this binding is essential for IGF2 signaling (PubMed:28873464).

Notes
Human Integrin beta 4 (Intracellular) SimpleStep ELISA® kit is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Integrin beta 4 (Intracellular) protein in human serum, plasma, saliva and cell culture supernatant. Quantitate Human Integrin beta 4 (Intracellular) with 0.033 ng/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
-Single-wash protocol reduces assay time to 90 minutes or less
-High sensitivity, specificity and reproducibility from superior antibodies
-Fully validated in biological samples
-96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (Pre-coated 384 well Microplate SimpleStep ELISA® ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.

- Activity summary
Integrin beta 4 also known as ITGB4 integrin ß4 or integrine beta 4 is a transmembrane protein that mechanically links the extracellular matrix to the intracellular cytoskeleton. This protein has a molecular mass of approximately 205 kDa. Integrin beta 4 primarily expresses in epithelial cells particularly those forming stratified and transitional epithelia. It partners with alpha 6 integrin to form the alpha 6 beta 4 integrin complex which plays a significant role in the formation and maintenance of hemidesmosomes.
- Biological function summary
Integrin beta 4 is important for anchoring epithelial cells to the basement membrane stabilizing cell layers in tissues. It interacts with intermediate filaments through specific cytoplasmic proteins. The integrin beta 4 complex ensures structural integrity essential for maintaining the skin and mucosal barriers. Integrations with proteins like M126 are essential for strengthening these interactions safeguarding cellular stability and promoting wound healing.
- Pathways
Integrin beta 4 is embedded in key signaling pathways that influence cell adhesion and migration. It participates prominently in the PI3K/AKT and RAS pathway collaborations facilitating signal transduction essential for cell growth and survival. Through these pathways integrin beta 4 interacts with proteins like IS200BPIRG1A linking extracellular cues to internal cellular responses.
- Associated diseases and disorders
Integrin beta 4 has associations with epidermolysis bullosa and various cancers. In epidermolysis bullosa mutations in integrin beta 4 impair hemidesmosomal function leading to skin fragility. In cancer integrin beta 4 overexpression or mislocalization contributes to tumor progression affecting cell invasion and metastasis. Its interactions with IS200BPIAG1A or related pathways highlight the protein’s influence on carcinogenic processes and potential as a therapeutic target.
