General annotation (Comments)

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.

Subunit structure

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 By similarity.

Subcellular location

Membrane; Single-pass type I membrane protein By similarity. Cell junction › hemidesmosome By similarity. Note: Colocalizes with DST at the leading edge of migrating keratinocytes By similarity.

Domain

The fibronectin type-III-like domains bind BPAG1 and plectin and probably also recruit BP230 By similarity.

Sequence similarities

Belongs to the integrin beta chain family.

Contains 1 Calx-beta domain.

Contains 4 fibronectin type-III domains.

Contains 1 PSI domain.

Contains 1 VWFA domain.
