Enables phosphatidylinositol binding activity. Predicted to be involved in phospholipid transport and signal transduction. Predicted to act upstream of or within phosphatidylinositol metabolic process. Located in cytoplasm and nucleus. Is expressed in several structures, including central nervous system; genitourinary system; liver; retina; and small intestine. Orthologous to human PITPNC1 (phosphatidylinositol transfer protein cytoplasmic 1). [provided by Alliance of Genome Resources, Apr 2022]
