Protein Biology

Function

Integrin alpha-6/beta-4 is a receptor for laminin. It 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. ITGA6:ITGB4 binds to IGF1 and this binding is essential for IGF1 signaling. ITGA6:ITGB4 binds to IGF2 and this binding is essential for IGF2 signaling

Subcellular Location

Cell membrane (Single-pass type I membrane protein); Cell membrane (Lipid-anchor); Cell junction, hemidesmosome

Subunit

Heterodimer of an alpha and a beta subunit. Beta-4 associates with alpha-6. Interacts (via cytoplasmic region) with COL17A1 (via cytoplasmic region). Interacts (via cytoplasmic region) with DST isoform 3 (via N-terminus). Interacts (via cytoplasmic domain) with DST (via N-terminus). Interacts with RAC1. ITGA6:ITGB4 is found in a ternary complex with NRG1 and ERBB3. ITGA6:ITGB4 is found in a ternary complex with IGF1 and IGF1R. ITGA6:ITGB4 interacts with IGF2 (By similarity). Interacts with TMEM268; this interaction prevents ITGB4 degradation (By similarity). Interacts (via C-terminus) with ARHGEF40 (via central region); the interaction may facilitate ITGB4 localization to hemidesmosomes and act as a linker to anchor keratin filaments to ITGB4 in hemidesmosomes (By similarity)
