Disruption of the normal biochemical processes that establish the levels of individual sphingolipids is associated with a variety of human diseases including cancer, cardiovascular disease, metabolic disease, skin diseases, and lysosomal storage diseases. A unique aspect of this metabolic network is that there is a single enzymatic step that initiates the biosynthetic pathway for all sphingolipids. This step is catalyzed by the enzyme serine palmitoyltranserase (SPT). Under most circumstances SPT condenses serine and the 16-carbon acyl-CoA, palmitoyl-CoA to produce the precursor of all sphingolipids. SPT, a four-subunit protein complex, is subject to classic feedback regulation: when cellular sphingolipids are elevated, SPT activity is inhibited. Ceramide is the sphingolipid sensed by this system and it regulates SPT by directly binding to the complex. The ceramide binding site in the SPT complex, and how ceramide binding results in SPT inhibition, has now been determined in vertebrates, plants, and yeast using molecular modeling and cryo-electron microscopy. Here we discuss the similarities and differences revealed by these resolved structures and the surprising result that ceramide binds at almost identical positions in the SPT complex of these divergent organisms, but accomplishes SPT regulation in very different ways.</p></div>","PeriodicalId":7214,"journal":{"name":"Advances in biological regulation","volume":"91 ","pages":"Article 101010"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138883866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are seven functionally distinct phosphoinositides, each derived via the reversible phosphorylation of phosphatidylinositol in various combinations on the inositol ring. Their generation and termination is tightly regulated by phosphatidylinositol-kinases and –phosphatases. These enzymes can function together in an integrated and coordinated manner, whereby the phosphoinositide product of one enzyme may subsequently serve as a substrate for another to generate a different phosphoinositide species. This regulatory mechanism not only enables the transient generation of phosphoinositides on membranes, but also more complex sequential or bidirectional conversion pathways, and phosphoinositides can also be transferred between organelles via membrane contacts. It is this capacity to fine-tune phosphoinositide signals that makes them ideal regulators of membrane organization and dynamics, through their recruitment of signalling, membrane altering and lipid transfer proteins. Research spanning several decades has provided extensive evidence that phosphoinositides are major gatekeepers of membrane organization, with roles in endocytosis, exocytosis, autophagy, lysosome dynamics, vesicular transport and secretion, cilia, inter-organelle membrane contact, endosome maturation and nuclear function. By contrast, there has been remarkably little known about the role of phosphoinositides at mitochondria – an enigmatic and major knowledge gap, with challenges in reliably detecting phosphoinositides at this site.</p><p>Here we review recent significant breakthroughs in understanding the role of phosphoinositides in regulating mitochondrial dynamics and metabolic function.</p></div>","PeriodicalId":7214,"journal":{"name":"Advances in biological regulation","volume":"91 ","pages":"Article 101001"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2212492623000477/pdfft?md5=213ae24683ebcf7cf751280c561481ab&pid=1-s2.0-S2212492623000477-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138497534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their production and activation are strictly regulated by highly elaborated mechanisms. Among them, those involving inositol lipids have drawn the attention of researchers. Phosphoinositides represent the seven combinatorially phosphorylated forms of the inositol head group of inositol lipids. They play a crucial role in regulating intracellular mechanisms, such as signal transduction, actin cytoskeleton rearrangements, and membrane trafficking, either by generating second messengers or by directly binding to specific domains of effector proteins. In this review, we will explore how phosphoinositides are implicated in controlling platelet production by megakaryocytes and in platelet activation processes. We will also discuss the diversity of phosphoinositides in platelets, their role in granule biogenesis and maintenance, as well as in integrin signaling.

Disruption of synaptojanin function has been implicated in a wide range of neurological disorders. Synaptojanins act as dual-functional lipid phosphatases capable of hydrolyzing a variety of phosphoinositides (PIPs) through autonomous <em>SAC1</em>-like PIP 4-phosphatase and PIP<sub>2</sub> 5-phosphatase domains. The rarity of an evolutionary configuration of tethering two distinct enzyme activities in a single protein prompted us to investigate their individual and combined roles in budding yeast. Both PIP and PIP<sub>2</sub> phosphatase activities are encoded by multiple gene products and are independently essential for cell viability. In contrast, we observed that the synaptojanin proteins utilized both lipid-phosphatase activities to properly coordinate polarized distribution of actin during the cell cycle. Expression of each activity untethered (<em>in trans</em>) failed to properly reconstitute the basal actin regulatory activity; whereas tethering (<em>in cis</em>), even through synthetic linkers, was sufficient to complement these defects. Studies of chimeric proteins harboring PIP and PIP<sub>2</sub> phosphatase domains from a variety of gene products indicate synaptojanin proteins have highly specialized activities and that the length of the linker between the lipid-phosphatase domains is critical for actin regulatory activity.
