Function

• may function as an adapter protein
• required for efficient phagocytosis of apoptotic cells
• modulates cellular glycosphingolipid & cholesterol transport
• may play a role in the internalization & endosomal trafficking of various LRP1 ligands, including PSAP
• increases cellular levels of GTP-bound ARF6
• interacts with clathrin
• interacts with GDP-bound ARF6, but not with GTP-bound ARF6
• part of a complex composed of GULP1, CENTB1 & ARF6
• interacts with CENTB1, LRP1 & MEGF10
