• The small guanosine triphosphate (GTP)-binding protein ADP-ribosylation factor (ARF) 6 regulates membrane recycling to regions of plasma membrane remodeling via the endocytic pathway. (silverchair.com)
  • Here, we show that GTP-bound ARF6 interacts with Sec10, a subunit of the exocyst complex involved in docking of vesicles with the plasma membrane. (silverchair.com)
  • Sec10 is found to redistribute to ruffling areas of the plasma membrane in cells expressing GTP-ARF6, whereas dominant inhibition of Sec10 interferes with ARF6-induced cell spreading. (silverchair.com)
  • The AP-1B clathrin adaptor complex plays a key role in the recognition and intracellular transport of many membrane proteins destined for the basolateral surface of epithelial cells. (rupress.org)
  • Expression of a constitutively activated GTP hydrolysis mutant selectively inhibited basolateral (but not apical) transport of newly synthesized membrane proteins. (rupress.org)
  • To a large extent, plasma membrane proteins are delivered to and maintained at the appropriate cell surface domain by distinct targeting signals that control polarized transport on the secretory and endocytic pathways ( Mellman, 1996 ). (rupress.org)
