Literature-anchored findings (GeneRIF, showing 10)

  • Stable expression of both viral GAAP (v-GAAP) and human GAAP (h-GAAP), which is expressed in all human tissues tested, inhibited apoptosis induced by intrinsic and extrinsic apoptotic stimuli (PMID:17319741)
  • The tmbim4 may participate in cell death regulation by interacting with proteins of Bcl-2 family, promoting tumor metastasis, which is deduced from the evolutionary conservation of the membrane protein family containing multiple membrane spanning segments (PMID:18440869)
  • Data demonstrate that h-GAAP modulates intracellular Ca(2+) fluxes induced by both physiological and apoptotic stimuli. (PMID:19553469)
  • Data indicate that GAAP and BI-1 have a six membrane-spanning topology with cytosolic N and C termini and a C-terminal reentrant loop. (PMID:22418439)
  • Taken together, the proposed interaction between Chlamydia pneumoniae protein CPn0809 and GAAP modulates bacterial growth in A549 cells. (PMID:23000903)
  • GAAP can oligomerize in a pH-regulated manner, and monomeric GAAP is functional. (PMID:23508950)
  • The hGAAP is a novel regulator of focal adhesion dynamics, cell adhesion, and migration by controlling localized Ca(2+)-dependent activation of calpain. (PMID:23940116)
  • These results suggest that the TMBIM family has comparable functions in the maintenance of intracellular Ca(2) homeostasis in a wide variety of tissues (PMID:25764978)
  • Residues contributing to the ion-conducting pore have been defined and provide the first clues about the mechanistic link between these very different functions of golgi anti-apoptotic protein (GAAP) [review]. (PMID:28469007)
