Predicted to enable several functions, including phosphatidylinositol-4-phosphate binding activity; sterol binding activity; and sterol transfer activity. Involved in positive regulation of insulin secretion involved in cellular response to glucose stimulus; positive regulation of secretory granule organization; and positive regulation of tyrosine phosphorylation of STAT protein. Located in cytosol. Orthologous to human OSBP (oxysterol binding protein). [provided by Alliance of Genome Resources, Apr 2022]
