Immunofluorescent colocalization of ARAP1 with DR4 at the plasma membrane and in early endosomes. ARAP1-transfected NCTC cells were treated with TRAIL for 0´, 30´ or 60´ and fixed with methanol. DR4 was detected by rabbit polyclonal (red) and MA1-19728 with ARAP1-2 mouse monoclonal antibody (green). Arrowheads show ARAP1-DR4 colocalization at the plasma membrane and intracellular membranes, whereas arrows show their colocalization in early endosomes.

ARAP1 (angiotensin II type 1 receptor-associated protein) is an adaptor protein with ArfGAP and RhoGAP activities, containing five PH domains and ankyrin repeate. This adaptor seems to serve as a link between phosphoinositide- Arf-, and Rho-mediated cell signaling. ARAP1 supports the plasma membrane recycling of angiotensin II type 1 receptor (AT1) and is important also for cell-specific trafficking of pro-death receptor TRAIL-R1 (DR4) to the plasma membrane, thus promoting the TRAIL-induced apoptosis in certain cell types. ARAP1 also affects cell spreading.
