High impact information on Rab7

 

Biological context of Rab7

 

Anatomical context of Rab7

  • Role for Rab7 in maturation of late autophagic vacuoles [11].
  • The expression of Rab7 was obviously increased in the hepatic tissues, especially in the endothelial cells and hepatocytes around central veins of the high cholesterol-fed rabbit, compared to the tissues from rabbit fed a normal diet [2].
  • Thus two Rab proteins regulate two different motor proteins, thereby controlling complementary phases in melanosome biogenesis: Rab7 controls microtubule-mediated transport of early and Rab27a the subsequent actin-dependent transport of mature melanosomes [12].
  • A cDNA clone coding for the Rab7 protein was isolated from an NIH3T3 cell line (mouse fibroblasts) cDNA library [13].
  • Here we report that removal of the carboxyl-terminal acidic Pro(505)AspGluAsnAsp(509) sequence prevents the storage of GLUT4 in the VAMP-2 positive compartment adjacent to the Golgi complex (GSC), and results in its targeting to GLUT4-positive vesicles and Rab7-positive late endosomes [14].
 

Associations of Rab7 with chemical compounds

  • Lm escaped from Rab5a-negative, lysosome-associated membrane protein-1 (LAMP1)-negative, Rab7-positive, phosphatidylinositol 3-phosphate [PI(3)P]-positive vacuoles [15].
  • Rab7 gene is up-regulated by cholesterol-rich diet in the liver and artery [2].
  • Nevertheless, despite acquisition of wild-type or constitutively active Rab7, both the L. pneumophila and the M. tuberculosis phagosomes continue to exhibit altered maturation as manifested by a failure to acquire lysosome-associated membrane glycoprotein 1 [5].
  • In growth factor-deprived cells, however, blocking Rab7 function prevented the clearance of glucose and amino acid transporter proteins from the cell surface [16].
 

Other interactions of Rab7

 

Analytical, diagnostic and therapeutic context of Rab7

  • By radiation hybrid mapping, we have located the human RAB7 gene on Chr 3, in a region homologous to the mouse Chr 6, where the Rab7 gene maps [10].
  • Our experiments with quantitative electron microscopy showed that Rab7 was not needed for the initial maturation of early autophagosomes to late autophagic vacuoles, but that it participated in the final maturation of late autophagic vacuoles [11].
  • Molecular cloning and expression analysis of the human Rab7 GTP-ase complementary deoxyribonucleic acid [21].
  • To visualize the location of elevated Rab7 expression in tissues, patterns of the gene expression were monitored within hepatic and aortic tissues by in situ hybridization and immunohistochemistry [2].
  • Western blot analysis reveals reduced Rab5 and enhanced Rab7 content in the maleylated bovine serum albumin-MDP (MBSA-MDP)-treated cells [3].
