High impact information on 128up

  • The intergenic distance between the 3' end of 128up mRNA and the 5' end of DmRP128 mRNA is only about 100 bp [1].
  • Bacterially expressed 128up protein fused to maltose-binding protein specifically binds GTP [1].
  • In accordance with the sequence conservation, antibodies against 128up specifically cross-react with mouse 3T3 cells and human Hep2 cells where the subcellular localization of the protein is predominantly perinuclear [1].
 

Analytical, diagnostic and therapeutic context of 128up

  • Sequence analysis of 128up cDNA reveals that the gene codes for a 41 kDa protein with homology to GTP-binding proteins and matching four of the structural sequence motifs characteristic of the superfamily of GTPases [1].
