Potent inhibitor of cell death. Inhibits activation of caspases (By similarity). Appears to regulate cell death by blocking the voltage-dependent anion channnel (VDAC) by binding to it and preventing the release of the caspase activator, CYC1, from the mitochondrial membrane.
Specificity
Natural and recombinant Rat Bcl-2-like protein 1
Subcellular Location
Mitochondrion membrane Single-pass membrane protein Nucleus membrane Single-pass membrane protein Cytoplasmic side Mitochondrial membranes and perinuclear envelope.
Homodimer (By similarity). Isoform Bcl-X(L) forms heterodimers with BAX, BAK or BCL2. Heterodimerization with BAX does not seem to be required for anti-apoptotic activity. Interacts with BAD and BBC3. Interacts (isoform Bcl-X(L)) with SIVA1 (isoform 1); the interaction inhibits the anti-apoptotic activity. Interacts with BECN1 and PGAM5. Interacts (isoform Bcl-X(L)) with BAX (isoform Sigma). Interacts with BCL2L11 (By similarity). Interacts with DMN1L; the interaction stimulates the GTPase activity of DMN1L in synapses and increases the number of axonal mitochondria and the size and number of synaptic vesicle clusters. Isoform Bcl-X(L) interacts with IKZF3.
