Predicted to enable fatty acid binding activity; lysophosphatidic acid acyltransferase activity; and protein homodimerization activity. Involved in positive regulation of neurotrophin TRK receptor signaling pathway; regulation of cell morphogenesis; and regulation of early endosome to late endosome transport. Located in several cellular components, including cytoplasmic vesicle; neuron projection; and neuronal cell body. Orthologous to human SH3GLB1 (SH3 domain containing GRB2 like, endophilin B1).
