Ceramide synthase 4 (Cers4)

May be either a bona fide (dihydro)ceramide synthase or a modulator of its action. When overexpressed in cells is involved in the production of sphingolipids containing different fatty acid donors (N-linked stearoyl- (C18) or arachidoyl- (C20) ceramides) in a fumonisin B1-independent manner.
