(e) Total cell lysate from (c) were immunoblotted with antibodies anti-E-cadherin, which recognize either an epitope in the cytoplasmic domain (IC), an epitope in the extracellular domain of mature E-cadherin (SHE78-7), respectively, or anti-RAB2A, and anti-actin. An arrow indicates the unprocessed form of E-cadherin.
