Recombinant Human Bcl-w

Description :
FAQ COA 已发表文献 Bcl-w (also known as Bcl-2 like protein 2, BCL2L2) is a member of the Bcl-2 family of proteins that regulates outer mitochondrial membrane permeability. Bcl-w is an anti-apoptotic member that prevents release of cytochrome c from the mitochondria intermembrane space into the cytosol. Bcl-w is required for normal sperm maturation. Natural Bcl-w contains a carboxyl-terminal mitochondria targeting sequence. Recombinant Bcl-w missing the mitochondrial targeting sequence maintains its ability to neutralize pro-apoptotic Bcl-2 family members. Neutralization by Bcl-w appears to be through binding the BH3 region of pro-apoptotic Bcl-2 family members. This activity does not require the mitochondrial targeting sequence.
