Enables acyltransferase activity. Predicted to be involved in phosphatidylinositol acyl-chain remodeling. Predicted to act upstream of or within phospholipid biosynthetic process. Located in endoplasmic reticulum. Is expressed in several structures, including arterial system; gonad; heart; immune system; and respiratory system. Orthologous to human LCLAT1 (lysocardiolipin acyltransferase 1). [provided by Alliance of Genome Resources, Apr 2022]
