General description【一般描述】 | A cell-permeable peptide that prevents apoptotic cell death by directly binding to the voltage-dependent anion channel (VDAC) and blocking its activity. Leads to the inhibition of cytochrome c release and loss of mitochondrial membrane potential (ΔΨm). Contains the conserved N-terminal homology domain (BH4) of Bcl-xL (amino acids 4 - 23) that has been shown to be essential for inhibiting VDAC activity in liposomes and in isolated mitochondria. The BH4 domain is linked to a carrier peptide, a 10-amino acid HIV-TAT48-57 sequence with a β-alanine residue as a spacer for maximum flexibility. Following its uptake, it is mainly localized to the mitochondria.
