Acylglycerol kinase, mitochondrial (AGK)

Lipid kinase that can phosphorylate both monoacylglycerol and diacylglycerol to form lysophosphatidic acid (LPA) and phosphatidic acid (PA), respectively (PubMed:15939762). Doesn't phosphorylate sphingosine (PubMed:15939762).

Independently of its lipid kinase activity, acts as a part of the TIM22 complex (PubMed:28712724, PubMed:28712726). The TIM22 complex mediates the import and insertion of multi-pass transmembrane proteins to the mitochondrial inner membrane by forming a twin-pore translocase which employs the membrane potential as the external driving force (PubMed:28712724, PubMed:28712726).
