Involved in vesicular recycling, probably as a RAB11B GTPase-activating protein. Interacts (via domain Rab-GAP TBC) with RAB11B (in GTP-bound form). Kidney (at protein level). Expressed in glomerular podocytes and tubules in the fetal kidney (gestational age 25 weeks)(at protein level). The arginine and glutamine fingers are critical for the GTPase-activating mechanism, they pull out Rab's 'switch 2' glutamine and insert in Rab's active site. The disease is caused by variants affecting the gene represented in this entry.
