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.

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.
