Abstract

ABSTRACTMembrane recycling is critical to numerous cell functions and its dysregulation contributes to cancer and metastasis. We established that activation of the transmembrane molecule aminopeptidase N (ANPEP, also known as CD13) tethers the IQ motif containing, guanosine triphosphate hydrolase activating protein 1 (IQGAP1) scaffolding protein at the plasma membrane, thus stimulating the recycling regulator ADP-ribosylation factor 6 (ARF6) to ensure proper recycling of β1-integrin and other membrane components impacting cell attachment.
