Gene Information

human ... BCL2L2(599)

General description

This recombinant Bcl-w lacks the mitochondrial targeting sequence but maintains the ability to neutralize pro-apoptotic Bcl-2 family members.

Biochem/physiol Actions

Like Bcl-2 and Bcl-x, the Bcl-w protein promotes cell survival, in contrast to other close homologues, Bax and Bak, which facilitate cell death. Bcl-w is an anti-apoptotic member of the Bcl-2 family that prevents release of cytochrome c from the mitochondrial intermembrane space into the cytosol. It is required for normal sperm maturation. Natural Bcl-w contains a C-terminal mitochondrial targeting sequence.

Physical form

Supplied as a 0.2 μm filtered solution in 25 mM HEPES, pH 7.5, 0.1 M KCl, and 10% glycerol.

Analysis Note

Measured by its ability to inhibit caspase-8-cleaved human BID-mediated release of cytochrome c from isolated mouse liver mitochondria using ELISA.

Bcl-w, a prosurvival member of the Bcl-2 family, is essential for spermatogenesis. However, the mechanisms by which Bcl-w participates in the regulation of apoptosis in the testis are largely unknown. To explore the potential role of Bcl-w in the regulation

B-cell lymphoma extra large (BCL-XL) is a well-validated cancer target. However, the on-target and dose-limiting thrombocytopenia limits the use of BCL-XL inhibitors, such as ABT263, as safe and effective anticancer agents. To reduce the toxicity of ABT263, we converted it
