What is VDAC1?
To understand these peptides, we must first look at the protein itself. VDAC1 (Voltage-Dependent Anion Channel 1) is a 31kDa protein located pri VDAC1 peptide - 279-0P marily in the mitochondrial outer membrane. It is a beta-barrel protein and acts as a non-selective voltage-gated by H Huang · 2025 · Cited by 1 — VDAC1, a pore protein located in the outer mitochondrial membrane, can regulate the voltage-gating activity to control OMM permeability and ion channel that mediates the transport of anions and cations through the mitochondrial outer membrane and plasma membrane.
Often referred to as a mitochondrial porin, VDAC1 is recognized as the most abundant pore-forming protein of the outer mitochondrial membrane. Because it serves as a mitochondrial gatekeeper, it is an important regulator of mitochondrial function and is essential for maintaining cellular energy production.
The Role of VDAC1 Peptides in Research
Scientific literature defines VDAC1 as a multi-functional mitochondrial protein that regulates cell life and death.

For example, studies have explored how cell-penetrating VDAC1 N-terminal-derived peptides can influence apoptosis, autophagy, and senescence. By interacting with the channel, these molecules can regulate the voltage-gating activity to control OMM permeability. This is particularly relevant in studies where VDAC1-based peptides induced cell death in various cancer cell lines, providing insights into how mitochondrial-dependent metabolic interference can be triggered in controlled environments.
