Disease relevance of TMEM132A

 

High impact information on TMEM132A

  • Because the sequence of GBP offered few clues to the possible function, we performed a GST-tagged GBP pull-down assay in PC12 lysates and identified GRP78, one of the heat shock proteins, as a counterpart [2].
  • Overexpression of GBP did not affect cell growth or morphological features but attenuated the time-dependent decrease in cell viability caused by serum deprivation compared with control cells [2].
  • After 48 h of serum starvation, Neuro2a cells overexpressing GBP were resistant to the cell death induced by serum withdrawal [2].
  • Observation of COS7 cells expressing green fluorescent protein- or Myc-tagged GBP showed that GBP was localized in the endoplasmic reticulum-Golgi domain where BODIPY 558/568 (4,4-difluro-5-(2-thienyl)-4-bora-3alpha,4alpha-diaza-S-indacene)-labeled brefeldin A accumulated [2].
  • It was shown that GAP possessed greater binding specificity than distamycin A, netropsin, Apy and GBP [3].
 

Associations of TMEM132A with chemical compounds

  • A pyrrolepolyamide-deoxyguanosine hybrid using the 3-aminopropyl linker (GAP) was designed and synthesized on the basis of previously reported results of a pyrrolepolyamide-adenosine hybrid (Apy) and a pyrrolepolyamide-deoxyguanoside hybrid using the 3-aminopropionyl linker (GBP) [3].
 

Analytical, diagnostic and therapeutic context of TMEM132A

  • Gastric bypass (RY-GBP) has a very small gastric pouch with a 1-cm diameter Roux-Y gastrojejunostomy [1].
