High impact information on Eef1a1

 

Biological context of Eef1a1

 

Anatomical context of Eef1a1

  • In adult mammalian tissues, isoform eEF1A-1 is present in all tissues except neurons, cardiomyocytes, and myotubes, where its isoform, eEF1A-2, is the only form expressed [7].
  • Here we show that Prdx-I coimmunoprecipitates with eEF1A-2 from extracts of both cultured cells and mouse tissues expressing this protein, but it does not do so with its isoform, eEF1A-1, even though the latter is abundantly present [7].
  • Both forms of eEF1A have been characterized to function in the protein elongation step of translation, and eEF1A-1 is shown to possess additional non-canonical roles in actin binding/bundling, microtubule bundling/severing, and cellular transformation processes [7].
  • Immuno-characterization of the switch of peptide elongation factors eEF1A-1/EF-1alpha and eEF1A-2/S1 in the central nervous system during mouse development [8].
  • Peptide elongation factor eEF1A-2/S1, which shares 92% homology with eEF1A-1/EF-1alpha, is exclusively expressed in brain, heart, and skeletal muscle [4].
 

Associations of Eef1a1 with chemical compounds

  • Several GTP binding proteins, including EF-Tu, Ypt1, rab-5, and FtsY, and adenylosuccinate synthetase have been reported to bind xanthine nucleotides when the conserved aspartate residue in the NKXD motif was changed to asparagine [9].
  • Two-dimensional gel electrophoretic (NEPHGE) analysis of proteins from mouse 3T3B and 3T3B/SV40 cells labelled with [methyl-3H]methionine in the presence of cycloheximide have revealed that the elongation factor 1 alpha (EF-1 alpha) in these cells is methylated and that the extent of methylation is higher in the SV40 transformed cell type [10].
  • Ethanolamine containing modifications of cytosolic proteins have only been described for elongation factor 1 alpha (EF-1 alpha) which contains two ethanolamine-phosphoglycerol moieties at Glu 301 and 374 (Whiteheart et al. (1989) J. Biol. Chem. 264, 14334-14341 and Dever et al. (1989) J. Biol. Chem. 264, 20518-20525) [11].
 

Other interactions of Eef1a1

  • The observed gradual decrease in FasL mRNA could not be attributed to a generalized degradation of cellular RNA during atresia, as evidenced by the presence of constitutive expression of elongation factor 1 alpha (EF-1 alpha) mRNA in murine ovaries and granulosa cells treated with PMSG [12].
  • The observed decreases in mRNA of Fas could not be attributed to a generalized degradation of cellular RNA during atresia, as evidenced by the presence of intact 18S and 28S ribosomal RNA as well as constitutive expression of EF-1 alpha mRNA in atretic follicles [13].
  • Furthermore, the alpha3/beta5 region corresponds to an exchange factor contact site in both EF-Tu and Ras, suggesting that the mechanisms by which seven-transmembrane receptors and exchange factors catalyze nucleotide exchange may share common elements [14].
  • Freshly isolated and thawed hepatocytes were transduced in suspension with lentiviral vectors expressing the GFP gene under the control of a ubiquitous promoter (EF1-alpha) and the apolipoprotein A-II promoter [15].
  • The mRNA for poly(A)-binding protein behaved similarly to EF-1 alpha [16].
