Figure 2. Interactions of HyBcl-2-4 with BH3 domain peptides of hydra encoded pro-apoptotic Bcl-2 proteins.
(a) ITC thermograms of the interaction between HyBcl-2-4 for BH3 domain peptides from hydra and human BH3 peptides (26-mers, except for a Bid 34-mer and Bax 28-mers). (b) Interactions of HyBcl-2-4 with BH3 domain peptides of human pro-apoptotic Bcl-2 proteins as well as interactions of human Bcl-2, Bcl-xL, Bcl-w, Mcl-1 and A1 with BH3 domain peptides of hydra encoded pro-apoptotic Bcl-2 proteins. All affinities were measured using ITC. Tabulation of affinity (KD) values (nM) are the means of 3 experiments ± SD. NB: no binding detected.
