amyloid beta-peptide | the addition of amyloid beta-peptide to normal brain decreases the PMCA activity resulting in the same Ca2+ dependency as that seen in Alzheimer's disease brain, whereas the addition of amyloid beta-peptide to Alzheimer's disease brain has no effect on PMCA activity, in the absence of cholesterol, the level of inhibition of cerebrum PMCA is 60%, but levels of inhibition decreases with increasing concentrations of cholesterol | Homo sapiens | |

amyloid beta-peptide 25-35 | a maximum inhibition of 75% is observed with 0.0025 mM amyloid beta-peptide 25-35 for PMCA reconstituted in phosphatidylcholine. | Homo sapiens | |
amyloid beta-peptide 25-35 | the activity of overexpressed PMCA4 in a microsomal fraction of the HEK-293 cells is inhibited by amyloid beta-peptide 25-35, a slight inhibition of the activity of PMCA3 is observed | Sus scrofa | |
additional information | no inhibition of isoforms PMCA4 and PMCA2 is observed with the amyloid beta-peptide 25-35. The addition of 0.0025 mM amyloid beta-peptide 25-35 to Alzheimer's disease brain has no effect on PMCA activity. No effect of amyloid beta-peptides is seen on SERCA or SPCA activity in either control or Alzheimer's disease brains | Homo sapiens | |
additional information | no inhibition of isoforms PMCA4 and PMCA2 is observed with the amyloid beta-peptide 25-35, 0.0025 mM amyloid beta-peptide 25-35 has no effect on the activity of PMCA purified from cerebellum | Sus scrofa | |
