Protein Structure
UniProt Annotation
Function Catalyzes specifically the phosphorylation of ceramide to form ceramide 1-phosphate. Acts efficiently on natural and analog 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 various sphingosines. Binds phosphoinositides. {ECO:0000269PubMed:19168031}.
Subcellular Localization Cytoplasm {ECO:0000269PubMed:19168031}. Membrane {ECO:0000269PubMed:19168031}; Peripheral membrane protein {ECO:0000269PubMed:19168031}.
Disease Associations
Tissue Specificity High level expression in heart, brain, skeletal muscle, kidney and liver; moderate in peripheral blood leukocytes and thymus; very low in spleen, small intestine, placenta and lung.
