Disease relevance of Slc35a2

  • 125I-Labeled Newcastle disease virus bound only poorly to gangliosides extracted from either FM3A or Had-1 cells on a high performance thin-layer chromatography plate [1].
  • These results suggest two possibilities by which UGT may mediate TMEV entry and infection [2].
  • These results further indicate that, with UGT deficiencies, HPPH potentially is a potent mediator of phenytoin-initiated genotoxicity and embryopathy, which may be relevant to teratogenesis and other adverse effects of phenytoin [3].
  • Phenytoin-initiated micronucleus formation was increased about 4-fold in both +/j (P = .006) and j/j (P = .009) UGT-deficient cells vs. +/+ UGT-normal cells, providing the first evidence that the bioactivation and oxidative toxicity of phenytoin itself may be avoided by direct N-glucuronidation, which was confirmed by tandem mass spectrometry [3].
  • CLO, PB, and PCN induced histological liver hypertrophy, increases in liver weights, in microsomal protein and cytochrome P450 contents as well as increases in specific UGT activities [4].
 

High impact information on Slc35a2

 

Biological context of Slc35a2

  • They were tested for genetic complementation in pairs by cell fusion and shown to fall into a single recessive complementation group, which was designated as Had-1 [6].
  • Reverse transcription polymerase chain reaction with primers that span the UGT open reading frame showed that three Lec8 mutants express a full-length open reading frame, while six Lec8 mutants predominantly express truncated UGT gene transcripts [7].
  • Thus, identifying point mutations that inactivate UGT in Lec8 mutants resulted in the discovery of amino acids that are critical to the activity of both UGT and CST, the two most divergent mammalian NSTs [7].
  • Now we have characterized its isoform, hUGT2, that is most likely generated through the alternative splicing of a transcript derived from the UGT genomic gene, that also codes for hUGT1 [8].
  • The glucuronidation kinetics of the prototypic substrates 4-methylumbelliferone (4MU) and 1-naphthol (1NP) by human UDP-glucuronosyltransferases (UGT) 1A1, 1A3, 1A4, 1A6, 1A7, 1A8, 1A9, 1A10, 2B7, 2B15, and 2B17 were investigated [9].
 

Anatomical context of Slc35a2

 

Associations of Slc35a2 with chemical compounds

  • The Had-1 mutant was resistant to wheat germ agglutinin, but sensitive to a Griffonia simplicifolia lectin, GS-II, which recognizes terminal N-acetylglucosamine residues [6].
  • Recent studies have demonstrated that UDP-galactose (UDP-Gal) is the substrate for the ER resident ceramide-galactosyltransferase (cer-GalT) and cells expressing cer-GalT are able to retain the UDP-Gal transporter (UGT) by physical contacts formed between the two proteins [11].
  • Among all UGT isoforms identified to date, it is the only relevant bilirubin-glucuronidating enzyme in human [14].
  • Phenytoin (80 microM) enhanced micronucleus formation 1.7-, 4.4- and 3.8-fold in +/+ cells (P = .03) and +/j and j/j UGT-deficient cells (P = .0001), respectively [3].
  • Exposure to BSO for 24 h produced a 75-85% depletion of GSH levels, proportional to the inhibition of GCS activity, as well as small increases in the UDP-glucuronosyltransferase (UGT, 60%) and glutathione transferase (GST, 30%) enzyme activities in Hepa-1 wild-type (wt) cells [15].

Analytical, diagnostic and therapeutic context of Slc35a2

  • Molecular cloning and characterization of a novel isoform of the human UDP-galactose transporter, and of related complementary DNAs belonging to the nucleotide-sugar transporter gene family [8].
  • RNA from 14 tissues was isolated from male and female C57BL/6 mice and UGT expression was determined by the branched DNA signal amplification assay [17].
  • Despite this, no significant changes in T4-UGT and T3-UGT activities occurred after treatment by any of these compounds [4].
  • These studies led us to develop a simple procedure, based on Percoll density gradient centrifugation, for preparing functional Golgi vesicles from the hUGT1-transformed Had-1 cells, that will facilitate future biochemical analyses of the UDP-galactose transporter for the elucidation of its structure-function relationship [18].
