Function
Acyltransferase required to remodel newly synthesized phospholipid cardiolipin (1',3'-bis-[1,2-diacyl-sn-glycero-3-phospho]-glycerol or CL), a key component of the mitochondrial inner membrane, with tissue specific acyl chains necessary for adequate mitochondrial function (PubMed:12930833, PubMed:19164547, PubMed:19700766, PubMed:26908608, PubMed:33096711). Its role in cellular physiology is to improve mitochondrial performance (PubMed:32234310). CL is critical for the coassembly of lipids and proteins in mitochondrial membranes, for instance, remodeling of the acyl groups of CL in the mitochondrial inner membrane affects the assembly and stability of respiratory chain complex IV and its supercomplex forms (By similarity). Catalyzes the transacylation between phospholipids and lysophospholipids, with the highest rate being between phosphatidylcholine (1,2-diacyl-sn-glycero-3-phosphocholine or PC) and CL. Catalyzes both 1-acyl-sn-glycero-3-phosphocholine (lysophosphatidylcholine or LPC) reacylation and PC-CL transacylation, that means, it exchanges acyl groups between CL and PC by a combination of forward and reverse transacylations. Also catalyzes transacylations between other phospholipids such as phosphatidylethanolamine (1,2-diacyl-sn-glycero-3-phosphoethanolamine or PE) and CL, between PC and PE, and between PC and phosphatidate (1,2-diacyl-sn-glycero-3-phosphate or PA), although at lower rate. Not regiospecific, it transfers acyl groups into any of the sn-1 and sn-2 positions of the monolysocardiolipin (MLCL), which is an important prerequisite for uniformity and symmetry in CL acyl distribution. Cannot transacylate dilysocardiolipin (DLCL), thus, the role of MLCL is limited to that of an acyl acceptor. CoA-independent, it can reshuffle molecular species within a single phospholipid class. Redistributes fatty acids between MLCL, CL, and other lipids, which prolongs the half-life of CL. Its action is completely reversible, which allows for cyclic changes, such as fission and fusion or bending and flattening of the membrane. Hence, by contributing to the flexibility of the lipid composition, it plays an important role in the dynamics of mitochondria membranes. Essential for the final stage of spermatogenesis, spermatid individualization (By similarity). Required for the initiation of mitophagy (PubMed:33096711). Required to ensure progression of spermatocytes through meiosis (By similarity). Exon 7 of human tafazzin is essential for catalysis (PubMed:19700766). Isoform 1. Catalyzes the transacylation between lysophosphatidate (such as 1-acyl-sn-glycero-3-phosphate) and phosphatidylglycerol (1,2-diacyl-sn-glycero-3-phospho-(1'-sn-glycerol)) (PubMed:19700766). Contributes to cardiolipin (1',3'-bis-[1,2-diacyl-sn-glycero-3-phospho]-glycerol or CL) remodeling (PubMed:12930833, PubMed:19700766). Isoform 3. Catalyzes the transacylation between lysophospholipids and phospholipids, and plays a fundamental role in cardiolipin (1',3'-bis-[1,2-diacyl-sn-glycero-3-phospho]-glycerol or CL) metabolism and remodeling. Isoform 5. Catalytically inactive. Isoform 7. Catalytically inactive.

- Activity summary
Tafazzin also known as TAZ is a mitochondrial phospholipid-lysophospholipid transacylase enzyme. It plays a role in the remodeling of cardiolipin a phospholipid found predominantly in the mitochondrial inner membrane. Tafazzin has a molecular mass of approximately 33 kDa. It is expressed in various tissues with higher expression levels found in tissues with high energy demands such as the heart and skeletal muscles.
- Biological function summary
Tafazzin is essential for maintaining mitochondrial function and energy production. It is a critical component of the system responsible for cardiolipin metabolism. The enzyme does not work alone; it interacts with other mitochondrial proteins to facilitate the proper composition of cardiolipin species necessary for mitochondrial structural integrity and functionality.
- Pathways
Tafazzin serves an important role in various lipid metabolism pathways. It participates in the phospholipid remodeling pathway where it interacts closely with acyltransferases to modify cardiolipin. This interaction is important for mitochondrial processes such as oxidative phosphorylation and energy conversion affecting proteins like cytochrome c oxidase and ATP synthase complex.
- Associated diseases and disorders
Tafazzin mutations are linked to Barth syndrome a rare genetic condition that affects the heart and muscles. This disorder is marked by symptoms including cardiomyopathy muscle weakness and neutropenia. Tafazzin dysfunction interrupts normal cardiolipin remodeling impacting proteins such as cytochrome c which contributes to abnormal energy metabolism seen in the syndrome. Additionally altered Tafazzin activity has connections to mitochondrial dysfunctions observed in some cardiomyopathies.
