May be required for normal outer mitochondrial membrane dynamics. Required for coatomer-mediated retrograde transport in certain cells. May recruit other proteins to membranes with high curvature. May promote membrane fusion. Binds DNM1, HTT, AMPH, BIN1 and ARFGAP1. Homodimer, and heterodimer with SH3GLB2. Binds BAX. Induction of apoptosis augments BAX binding. Highly expressed in heart, skeletal muscle, kidney and placenta. Detected at lower levels in brain, colon, thymus, spleen, liver, small intestine, lung and peripheral blood leukocytes. Belongs to the endophilin family. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
