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 (By similarity). {ECO:0000250}.

Subcellular Localization

Cell membrane {ECO:0000250}; Single-pass type I membrane protein {ECO:0000250}. Cell membrane {ECO:0000250}; Lipid-anchor {ECO:0000250}. Cell junction, hemidesmosome {ECO:0000250}. Note=Colocalizes with DST at the leading edge of migrating keratinocytes. {ECO:0000250}.
