-
calcium ionophore, 216% activation of ceramide kinase in A549 lung adenocarcinoma cells
Ca2+
1 mM, stimulatory effect in the absence of Mg2+
Calcium
-
-
Calmodulin
-
binding site is located at residues 422-435, which form a amphipathic helical wheel, motif 1-8-14, calmodulin is involved in the Ca2+-dependent activation of ceramide kinase as a calcium-sensor
interleukin-1 beta
-
187% activation of ceramide kinase in A549 lung adenocarcinoma cells
-
Mg2+
3 mM, highly dependent on Mg2+
peroxisome proliferator-activated receptor beta
-
upregulation of CERK through activation of peroxisome proliferator-activated receptor beta (PPARbeta) results in decreased intracellular ceramide levels and increased cell survival with less cell death
-
Phorbol esters
-
e.g. PMA
