CC -!- FUNCTION: Catalyzes specifically the phosphorylation of ceramide to
CC form ceramide 1-phosphate (PubMed:16269826). Acts efficiently on
CC natural and analog ceramides (C6, C8, C16 ceramides, and C8-
CC dihydroceramide), to a lesser extent on C2-ceramide and C6-
CC dihydroceramide, but not on other lipids, such as various sphingosines
CC (PubMed:16269826). Shows a greater preference for D-erythro isomer of
CC ceramides (By similarity). Binds phosphoinositides (By similarity).
