GTPase activating protein that acts on ARF6. Plays a role in clathrin-dependent endocytosis. May play a role in erythropoiesis. Interacts with ARF6. Interacts with clathrin heavy chains via the clathrin box-like motif. Detected in adult brain, lung, heart, liver, ovary and bone marrow. Detected in stromal cells of the red pulp of adult spleen. Detected in stromal cells of fetal liver at 10.5 days. Expression was maximal after 14 days of development and decreased thereafter. Detected at low levels after 18 days. Contaminating sequence. Potential poly-A sequence.
