J-Mark P4-MP Driver
Phospholipid Asymmetry in Biological Membranes Inthe scientists Gorter and Grendel were the first to demonstrate that the plasma membrane of the erythrocyte was a bilayer of phospholipids [ 1 ]. Indeed, biological membranes are an intricate mixture of many different lipid species that are J-Mark P4-MP as two back-to-back facing leaflets of phospholipids with hydrophilic head groups facing the hydrophilic environment and hydrophobic acyl tails facing the core of the J-Mark P4-MP [ 2 ].
Most glycerophospholipids are synthesized in the endoplasmic J-Mark P4-MP ERwhile sphingolipids are synthesized in the Golgi.
Cardiolipin, a glycerophospholipid exclusively localized to the inner membrane of mitochondria, is manufactured in the mitochondrion. Each leaflet has a different composition which also varies from organelle to organelle. One of the hallmarks of eukaryotic membranes in the secretory and endocytic pathways is the asymmetric distribution of the different phospholipid species over the exoplasmic- and cytoplasmic leaflet of the bilayer. Maintaining and dissipating the non-random distribution J-Mark P4-MP phospholipids is crucial for normal regulated membrane protein J-Mark P4-MP.
For instance, J-Mark P4-MP exposure at the plasma membrane is an important signal both in the recognition and phagocytosis of apoptotic cells and in the activation of blood coagulation [ 4 ]. In the cytosolic leaflet of the plasma J-Mark P4-MP, PS is important for the recruitment J-Mark P4-MP protein kinase C PKCSrc, Ras and Rho proteins via binding to their C2 domain or other cationic domains [ 56 ].
In the early s, Bretscher, Gordesky and Marinetti demonstrated that the aminophospholipids PS and PE are concentrated in the cytoplasmic leaflet of the erythrocyte bilayer [ 78 ].
In addition, Verkleij J-Mark P4-MP al. Less abundant phospholipids, like PI and derivatives of PI and phosphatidic acid PA are mostly confined to the cytoplasmic leaflet [ 10 — 12 ]. Cholesterol can partition equally and J-Mark P4-MP milliseconds to seconds between the two leaflets [ 13 ].
It may be enriched in the exoplasmic leaflet due to its high affinity for SM [ 14 ], although fluorescent sterols have been predominantly localized to the cytosolic leaflet in J-Mark P4-MP Hamster Ovary cells [ 15 J-Mark P4-MP. Differences in membrane J-Mark P4-MP composition likely alter the chemical stability of cholesterol leading to differences in cholesterol distribution, as discussed in [ 16 ]. For instance, when the phosphatidyl head group is removed from the glycerol backbone of phosphatidylthioglycerol a phosphatidylglycerol analog and is subsequently replaced by dioleoylthioglycerol a diacylglycerol analogits unaided translocation rate was decreased from eight days to fifteen seconds [ 18 ].
J-Mark P4-MP, the non-random transbilayer distribution J-Mark P4-MP phospholipids must be actively maintained, which is accomplished by phospholipid translocating proteins termed flippases and floppases. Lipid flippases and floppases are ATP-dependent proteins that confer transbilayer distribution of phospholipids by translocating phospholipids from the exoplasmic to the cytoplasmic leaflet of the bilayer and vice versa, respectively [ 19 ].
Thus, chromatin remodeling and post-translational modification of histones and chromatin-bound proteins are now being recognized as J-Mark P4-MP mechanisms integrating local chromatin architecture with repair pathway choice. Chromatin modifications also play a central role in HR-mediated ejection of 53BP1.
It is therefore J-Mark P4-MP increasingly clear that protein modifications act as dynamic platforms promoting the assembly and disassembly of protein complexes, modulating enzymatic activity, and signaling pathway choice. One modification that we know very little J-Mark P4-MP, particularly within the context of the DNA damage response, is arginine methylation. Dimethylation can occur asymmetrically ADMAwith two methyl groups placed onto one of the terminal nitrogen atoms J-Mark P4-MP the guanidino group, or symmetrically SDMAwhere one methyl group is placed onto each of the terminal nitrogen atoms.
Recently, a number of studies have demonstrated a role for the main asymmetric arginine methyltransferase PRMT1 in the maintenance of genomic stability and the DNA damage response Auclair and Richard, Our results thus demonstrate J-Mark P4-MP importance of arginine methylation for DSB pathway choice, and we identify a mechanism by which arginine methylation can specifically direct J-Mark P4-MP activity of a critical DNA repair complex that is known to have multiple roles within the DNA damage response.
