αvβ8 integrin and Band 4.1B CTD physically associate in transfected mammalian cells. (A) V5- and myc-tagged constructs used for transfection and coimmunoprecipitation analysis. (B and C) β8-V5 interacts with Band 4.1B via the Band 4.1B CTD encoded by exons 20 and 21. As shown in B, αvβ8-V5 coimmunoprecipitates with full length Band 4.1B-myc or with the CTD region encoded by exons 20 and 21 (CTDex20-21-myc). No interaction is detected between αvβ8-V5 and the Band 4.1B FERM-myc or the lacZ-myc control. (C) Relative amounts of myc-tagged proteins were immunoprecipitated the various transfected cell lysates.
