Ceramide kinase (CERK)

Catalyzes especially the phosphorylation of ceramide to form ceramide 1-phosphate. Acts efficiently on analog and natural ceramides (C6, C8, C16 ceramides, and C8-dihydroceramide), to a lesser extent on C2-ceramide and C6-dihydroceramide, but not on other lipids, such as many sphingosines.

Binds phosphoinositides. .
