Predicted to enable calcium ion binding activity; phospholipid binding activity; and syntaxin binding activity. Predicted to be involved in several processes, including dense core granule maturation; positive regulation of secretion by cell; and regulation of dense core granule exocytosis. Predicted to act upstream of or within G protein-coupled receptor signaling pathway. Predicted to be located in several cellular components, including GABA-ergic synapse; endosome membrane; and trans-Golgi network membrane. Orthologous to human BAIAP3 (BAI1 associated protein 3).
