== Function ==
[https://www.uniprot.org/uniprot/B2CL1_HUMAN B2CL1_HUMAN] Potent inhibitor of cell death. Inhibits activation of caspases (By similarity). Appears to regulate cell death by blocking the voltage-dependent anion channel (VDAC) by binding to it and preventing the release of the caspase activator, CYC1, from the mitochondrial membrane. Also acts as a regulator of G2 checkpoint and progression to cytokinesis during mitosis.<ref>PMID:19917720</ref> <ref>PMID:21840391</ref>  Isoform Bcl-X(S) promotes apoptosis.<ref>PMID:19917720</ref> <ref>PMID:21840391</ref>

== Publication Abstract from PubMed ==
Cells expressing high levels of the BCL-X(L) anti-apoptotic protein are preferentially killed by the mitochondrial inhibitor antimycin A (AA). Computational modeling predicts a binding site for AA in the extended hydrophobic groove on BCL-X(L), previously identified as an interface for dimerization to BAX and related proapoptotic proteins. Here, we identify BCL-X(L) hydrophobic groove mutants with normal cellular anti-apoptotic function but suppressed sensitivity to AA. The LD(50) of AA for cells expressing BCL-X(L) mutants directly correlates with the measured in vitro dissociation constants for AA binding. These results indicate that BCL-X(L) is a principal target mediating AA cytotoxicity.
