Lipid kinase that can phosphorylate both monoacylglycerol and diacylglycerol to form lysophosphatidic acid (LPA) and phosphatidic acid (PA), respectively (By similarity). Phosphorylates ceramide but not sphingosine (By similarity). Phosphorylates 1,2-dioleoylglycerol more rapidly than 2,3-dioleoylglycerol (By similarity). Independently of its lipid kinase activity, acts as a component of the TIM22 complex (By similarity). The TIM22 complex mediates the import and insertion of multi-pass transmembrane proteins into the mitochondrial inner membrane by forming a twin-pore translocase that uses the membrane potential as the external driving force (By similarity). a monoacylglycerol + ATP = ADP + H(+) + monoacyl-sn-glycero-3-phosphate a 1,2-diacyl-sn-glycerol + ATP = a 1,2-diacyl-sn-glycero-3-phosphate + ADP + H(+) an N-acylsphing-4-enine + ATP = ADP + an N-acylsphing-4-enine 1-phosphate + H(+) 1-(9Z-octadecenoyl)-sn-glycerol + ATP = 1-(9Z-octadecenoyl)-sn-glycero-3-phosphate + ADP + H(+) 1,2-di-(9Z-octadecenoyl)-sn-glycerol + ATP = 1,2-di-(9Z-octadecenoyl)-sn-glycero-3-phosphate + ADP + H(+) a 1-acyl-sn-glycerol + ATP = a 1-acyl-sn-glycero-3-phosphate + ADP + H(+) 1-hexadecanoyl-sn-glycerol + ATP = 1-hexadecanoyl-sn-glycero-3-phosphate + ADP + H(+) 2-(5Z,8Z,11Z,14Z-eicosatetraenoyl)-glycerol + ATP = 2-(5Z,8Z,11Z,14Z-eicosatetraenoyl)-sn-glycero-3-phosphate + ADP + H(+) 1-(5Z,8Z,11Z,14Z-eicosatetraenoyl)-sn-glycerol + ATP = 1-(5Z,8Z,11Z,14Z-eicosatetraenoyl)-sn-glycero-3-phosphate + ADP + H(+) ATP + N-(hexanoyl)sphing-4-enine = ADP + H(+) + N-hexanoylsphing-4-enine 1-phosphate Lipid metabolism; glycerolipid metabolism. Component of the TIM22 complex. Localizes in the mitochondrion intermembrane space, where it associates with the inner membrane. It is unclear whether the N-terminal hydrophobic region forms a transmembrane region or associates with the membrane without crossing it. Belongs to the AGK family.
