Most phospholipids are derivatives of glycerol comprising two fatty acyl residues (nonpolar tails) and a single phosphate ester substituent (polar head group). (thermofisher.com)
Phospholipids2
Certain fluorescent fatty acids ( Fatty Acid Analogs and Phospholipids-Section 13.2 ) are readily metabolized by live cells to phospholipids, mono-, di- and triacylglycerols, cholesteryl esters and other lipid derivatives. (thermofisher.com)
Lipids also encompass molecules such as fatty acids and their derivatives (including tri- , di- , and monoglycerides and phospholipids ), as well as other sterol -containing metabolites such as cholesterol . (wikidoc.org)
Phosphatidic1
In addition to serving as a primary component of cellular membranes and binding sites for intra- and intercellular proteins, some glycerophospholipids in eukaryotic cells, such as phosphatidylinositols and phosphatidic acids are either precursors of, or are themselves, membrane-derived second messengers.

Cyclitol4
Synthesis of new cyclitol compounds that influence the activity of phosphatidylinositol 4-kinase isoform, PI4K230. (embl.de)

Some of the prepared cyclitol derivatives (i.e. 9, 11, 12, and 14) proved to be very powerful and specific irreversible inhibitors of PI4K230 at or below a concentration of 1 mM. (embl.de)
It has been known that the binding of IP6, an abundant endogenous cyclitol molecule at the MA domain, has been linked to the oligomerization of Pr55Gag. (bvsalud.org)
Molecules1
Here, we present three high-resolution crystal structures of the MA domain in complex with IP6 molecules to reveal its binding mode. (bvsalud.org)
Proteins1
The recruitment of specific cytosolic proteins to intracellular membranes through binding phosphorylated derivatives of phosphatidylinositol (PtdIns) controls such processes as endocytosis, regulated exocytosis, cytoskeletal organization, and cell signaling. (embl.de)
Fatty acids1
Although fatty acids are ionized at neutral pH in water (pK a ~5), their pK a is typically ~7 in membranes, and thus a significant fraction of membrane-bound fatty acids are neutral species. (thermofisher.com)
Residues2
Additionally, extensive Differential Scanning Fluorimetry analysis combined with cryo- and ambient-temperature X-ray crystallography and GNM-based transfer entropy calculations identify the key residues that participate in IP6 binding. (bvsalud.org)
IP6 and PIP2 have neighboring alternate binding sites within the same highly basic region (residues 18-33). (bvsalud.org)

Reveal1
In addition, the double mutant (Y42A/L48Q) of the PX domain of Vam7p, reported to cause vacuolar trafficking defects in yeast, has a dramatically decreased level of binding to PtdIns-3-P. These data reveal that the membrane targeting function of the Vam7p PX domain is based on its ability to associate with PtdIns-3-P, analogous to the function of FYVE domains. (embl.de)
Level2
An increase in the level of active, GTP-bound Ras is not necessary for transformation of chicken embryo fibroblasts (CEF) by v-Src. (embl.de)
Study reports suggested that high blood level of phosphate causes vascular ossification through the deposition of Ca 2+ and substantially alters fibroblast growth factor-23 (FGF23) and calcitriol. (diabeets.com)
Addition1
In addition, communities and even health experts, including medical doctors, are not well-informed about the adverse effects of phosphate preservatives on human health. (diabeets.com)
Domain2
The PX domain of Vam7p selectively binds PtdIns-3-P, while the PX domain of the CPK PI-3 kinase selectively binds PtdIns-4,5-P(2). (embl.de)
In contrast, the PX domain of Vps5p displays no binding to any PtdInsPs that were tested. (embl.de)
Mutagenesis3
Mutagenesis of the basic residues that form ionic interactions with the D3 and D4 phosphate groups reduces or abolishes the ability of PKB to interact with PtdIns(3,4,5)P3 and PtdIns(3,4)P2. (nih.gov)
Systematic deletion mutagenesis of Tsp localized the binding site to amino acids 206-307, a region that completely encompasses the putative PDZ domain (217-301). (embl.de)
Site-directed mutagenesis of a surface residue at the peptide binding site of the PDZ domain, valine 229, to Glu or Gln resulted in an increase in the K(M) value but had no effect on the k(cat) value. (embl.de)
Ligand2
Peptide binding of the ligand takes place in an elongated surface groove as an anti-parallel beta-strand interacts with the beta-B strand and the B helix. (embl.de)
Ligand 2-arachidonoylglycerol phosphorylates a abasic bind in NOTCH3, which stops the lysosomal thrombosis in the GM1 order of NOTCH3. (evakoch.com)
Peptide3
The structure of PDZ domains allows binding to a free carboxylate group at the end of a peptide through a carboxylate-binding loop between the beta-A and beta-B strands. (embl.de)
The isolated PDZ domain (amino acids 206-334) is capable of folding into a well-behaved structure and binds to a nonpolar peptide with a dissociation constant (K(D)) of 1.9 microM, similar to that of the intact Tsp protein. (embl.de)
