puma bh3 (tfa)

PUMA BH3 (TFA) is a p53 upregulated modulator of apoptosis (PUMA) BH3 domain peptide, acts as a direct activator of Bak, with a Kd of 26 nM.

PUMA BH3 (TFA), a peptide from the BH3 domain of the p53 upregulated modulator of apoptosis (PUMA), directly activates Bak with a dissociation constant (Kd) of 26 nM [1].

PUMA BH3, a peptide that includes the BH3 domain from the p53-upregulated modulator of apoptosis (PUMA) and activates the pro-apoptotic protein Bak, demonstrates binding affinity to Bak with dissociation constants (Kds) of 290 nM in HEPES buffer and 26 nM in CHAPS buffer. This interaction with Bak induces its homo-oligomerization and facilitates Bak-mediated membrane permeabilization.
