Peptide Sequences and Expected Behavior in BH3 Profiles
Peptidea | Sequenceb | Classc | Expected Behaviord |
---|---|---|---|
BIM | MRPEIWIAQELRRIGDEFNA | A | Rapid depolarization when BAX and BAK are present/functional |
BID-Y | EDIIRNIARHLAQVGDSMDRY | A | |
PUMA | EQWAREIGAQLRRMADDLNA | S | Depolarizes primed cells. Pan-sensitizers. Generally depolarize next after BIM / BID |
BMF-Y | HQAEVQIARKLQLIADQFHRY | S | |
BAD | LWAAQRYGRELRRMSDEFEGSFKGL | S | Depolarization if dependent on BCL2, BCL-W, or BCL-xL |
NOXAA | AELPPEFAAQLRKIGDKVYC | S | Depolarization only if dependent on MCL1 |
W-HRK | WSSAAQLTAARLKALGDELHQ | S | Depolarization only if dependent on BCL-xL |
PUMA2A | EQWAREIGAQARRMAADLNA | Control | Mutant control peptide. No depolarization |
–Y and W- denote amino acids added to the sequence for UV absorbance measurement of peptide concentration.
All have Acetyl N-termini and Amidated C-termini.
A=Activator, S=Sensitizer.
At 10-100 uM. Combining NOXAA+BAD peptides mimics PUMA
