Related Product Information for ITGB4 recombinant protein

ITGB4, also known as integrin beta-4 isoform 1, is a member of the Integrin beta family. It forms noncovalent heterodimers with Integrin alpha 6 and participates in the formation of epithelial hemidesmosomes. This protein plays a critical structural role in the hemidesmosome of epithelial cells and is required for the regulation of keratinocyte polarity and motility. The heterodimer of them binds to NRG1 and this binding is essential for NRG1-ERBB signaling and binds to IGF1 and this binding is essential for IGF1 signaling. It tends to associate with alpha 6 subunit and is likely to play a pivotal role in the biology of invasive carcinoma. Recombinant human ITGB4 protein, fused to His-tag at C-terminus, was expressed in insect cell and purified by using conventional chromatography techniques.

NCBI Description

Integrins are heterodimers comprised of alpha and beta subunits, that are noncovalently associated transmembrane glycoprotein receptors. Different combinations of alpha and beta polypeptides form complexes that vary in their ligand-binding specificities. Integrins mediate cell-matrix or cell-cell adhesion, and transduced signals that regulate gene expression and cell growth. This gene encodes the integrin beta 4 subunit, a receptor for the laminins. This subunit tends to associate with alpha 6 subunit and is likely to play a pivotal role in the biology of invasive carcinoma. Mutations in this gene are associated with epidermolysis bullosa with pyloric atresia. Multiple alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.

Uniprot Description

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).
