CC -!- FUNCTION: INTEGRIN ALPHA-6/BETA-4 MAY MEDIATE ADHESIVE AND/OR CC MIGRATORY FUNCTIONS OF EPITHELIAL CELLS. ON PLATELETS, INTEGRIN CC ALPHA-6/BETA-1 FUNCTIONS AS A LAMININ RECEPTOR. CC -!- SUBUNIT: DIMER OF AN ALPHA AND BETA SUBUNIT. ALPHA-6 CAN CC ASSOCIATE WITH BETA-1 (FORMING THE PLATELET LAMININ RECEPTOR) CC OR BETA-4 (PREDOMINANTLY ON EPITHELIAL CELLS). CC -!- SUBUNIT: THE ALPHA SUBUNIT MAY BE CLEAVED POST-TRANSLATIONALLY CC TO GIVE TWO POLYPEPTIDES JOINED BY A DISULFIDE BRIDGE. CC -!- SUBCELLULAR LOCATION: TYPE I MEMBRANE PROTEIN. CC -!- TISSUE SPECIFICITY: INTEGRIN ALPHA-6/BETA-4 IS PREDOMINANTLY CC EXPRESSED BY EPITHELIA. CC -!- PTM: PHOSPHORYLATED IN VIVO. CC -!- SIMILARITY: WITH OTHER ALPHA CHAINS FROM THE INTEGRIN FAMILY OF CC CELL-SURFACE RECEPTOR.
