Predicted to enable protein homodimerization activity. Predicted to be involved in SNARE complex assembly; positive regulation of L-proline import across plasma membrane; and regulation of transmembrane transporter activity. Predicted to act upstream of with a positive effect on calcium-ion regulated exocytosis and insulin secretion involved in cellular response to glucose stimulus. Predicted to be located in brush border membrane and cytoplasm. Predicted to be active in plasma membrane. Orthologous to human CLTRN (collectrin, amino acid transport regulator).
