General annotation (Comments)

Function	Can activate specifically hydrolysis of GTP bound to RAC1 and CDC42, but not RALA. Mediates ATP-dependent transport of S-(2,4-dinitrophenyl)-glutathione (DNP-SG) and doxorubicin (DOX) and is the major ATP-dependent transporter of glutathione conjugates of electrophiles (GS-E) and DOX in erythrocytes. Can catalyze transport of glutathione conjugates and xenobiotics, and may contribute to the multidrug resistance phenomenon. Serves as a scaffold protein that brings together proteins forming an endocytotic complex during interphase and also with CDC2 to switch off endocytosis, One of its substrates would be EPN1/Epsin. Ref.1 Ref.5 Ref.6
Subunit structure	Interacts with the GTP-bound form of RALA, RALB, CDC42 and RAC1. Interacts with REPS1 and REPS2 and this does not affect the Ral-binding activity. Interacts with DAB2IP. Interacts with catalytically active CCNB1 and CDC2 during mitosis. Interacts with EPN1, NUMB and TFAP2A during interphase and mitosis. Ref.1 Ref.5 Ref.4 Ref.7
Subcellular location	Membrane; Peripheral membrane protein Ref.6.
Tissue specificity	Expressed ubiquitously but at low levels. Shows a strong expression in the erythrocytes. Ref.6
Sequence similarities	Contains 1 Rho-GAP domain.
