CLN6 is a glycerophosphoglycerol epimerase in bis(monoacylglycero)phosphate biosynthesis

Pradeep Kumar Sheokand, Andrew M. James, Christian Posern, Amit Singh, Johannes Breithofer, Joe Ganellin, McKayla K. Proulx, Susannah K. Leese, Keira Turner, Denis Lacabanne, Dominik Bulfon, Benjamin Jenkins, Joris van der Kleij, Harvey E. Johnston, Samuel O. Lord, , Kasparas Petkevicius

This study identifies CLN6 as a glycerophosphoglycerol epimerase essential for BMP biosynthesis, showing its deficiency disrupts lysosomal hydrolase homeostasis and can be reversed by BMP precursor supplementation.

Acid phospholipase A1 promotes lysosomal membrane catabolism

Martin Tischitz, Johannes Breithofer, Dominik Bulfon, Clara Zitta, Amit Singh, Carina Wagner, Nermeen Fawzy, Thomas Züllig, Monika Oberer, Lennart Hartig, Anita Pirchheim, Laszlo Schooltink, Ulrike Taschler, Karl F. Gruber, Achim Lass, , Robert Zimmermann

This study identifies acid phospholipase A1's role in lysosomal glycerophospholipid catabolism and shows its interaction with bis(monoacylglycero)phosphate and inhibition by cationic amphiphilic drugs.

CLN8 enables a non-canonical phospholipid synthesis pathway

Johannes Breithofer, Nermeen Fawzy, Clara Zitta, Martin Tischitz, Dominik Bulfon, Clemens Hofmann, Lennart Hartig, Carina Wagner, Gernot F. Grabner, Anita Pirchheim, Achim Lass, Ulrike Taschler, Keira Turner, Kasparas Petkevicius, Ulrich Stelzl, , Robert Zimmermann

The paper describes a non-canonical phospholipid synthesis pathway catalyzed by CLN8, leading to BMP synthesis and revealing its role in lysosomal lipid homeostasis and Batten disease.

The endolysosomal phospholipid bis(monoacylglycero)phosphate is synthesized via intra- and extracellular pathways

Dominik Bulfon, Johannes Breithofer, Gernot F. Grabner, Nermeen Fawzy, Anita Pirchheim, Heimo Wolinski, Dagmar Kolb, Lennart Hartig, Martin Tischitz, Clara Zitta, Greta Bramerdorfer, Achim Lass, Ulrike Taschler, Dagmar Kratky, Peter Greimel, Robert Zimmermann

This study identifies cytosolic and secreted transacylases that synthesize bis(monoacylglycero)phosphate (BMP) independently of CLN5, correcting BMP deficiency in CLN5-deficient cells.
