Target data

Function

Potent inhibitor of cell death. Inhibits activation of caspases. 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.Isoform Bcl-X(L) also regulates presynaptic plasticity, including neurotransmitter release and recovery, number of axonal mitochondria as well as size and number of synaptic vesicle clusters. During synaptic stimulation, increases ATP availability from mitochondria through regulation of mitochondrial membrane ATP synthase F(1)F(0) activity and regulates endocytic vesicle retrieval in hippocampal neurons through association with DMN1L and stimulation of its GTPase activity in synaptic vesicles. May attenuate inflammation impairing NLRP1-inflammasome activation, hence CASP1 activation and IL1B release (PubMed:17418785).Isoform Bcl-X(S) promotes apoptosis.

Notes

ab223547 is the carrier-free version of ab178844.

Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

This product is a recombinant monoclonal antibody, which offers several advantages including:

  • - High batch-to-batch consistency and reproducibility
  • - Improved sensitivity and specificity
  • - Long-term security of supply
  • - Animal-free batch production

For more information, read more on recombinant antibodies.

Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.

This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.

Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with 1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.

This product is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm, without the need for antibody preparation. Maxpar® is a trademark of Fluidigm Canada Inc.

Supplementary info

Biological function summary

This protein acts as an anti-apoptotic molecule within the mitochondria and is part of the Bcl-2 family complex. Bcl-XL modulates the balance between pro-apoptotic and anti-apoptotic signals impacting cell fate. By binding and sequestering pro-apoptotic members such as Bax and Bak Bcl-XL prevents mitochondrial outer membrane permeabilization important for avoiding programmed cell death. This function not only supports cellular longevity but also understanding cancer cell survival.

Activity summary

Bcl-XL also known as Bcl-xL or Bcl-Xl protein is a member of the Bcl-2 protein family playing an important role in regulating cell death. Bcl-XL inhibits apoptosis by binding to pro-apoptotic proteins preventing the release of cytochrome c from mitochondria. This protein has a molecular weight of approximately 30 kDa. Bcl-xL is widely expressed in tissues notably in the brain endothelial cells and hematopoietic tissues where it contributes to cell survival.

Pathways

The Bcl-XL protein holds a significant position in the apoptotic signaling pathways. It is particularly involved in the intrinsic pathway where its interactions with mitochondrial proteins Bax and Bak determine cell survival or death. It is interconnected with the PI3K/AKT pathway where AKT kinase activity can upregulate Bcl-XL expression demonstrating how survival signals are transmitted. These interactions highlight its pivotal role in balancing life and death at the cellular level.

Associated diseases and disorders

Bcl-XL's overexpression often connects to the progression of cancers and resistance to chemotherapy. By inhibiting programmed cell death Bcl-XL allows cancer cells to evade traditional treatments. Furthermore research implicates Bcl-XL in neurodegenerative disorders where its interaction with Bcl-2 proteins disrupts normal apoptotic processes contributing to cellular dysfunction and disease. Understanding Bcl-XL's disease-related roles furthers the development of targeted therapies combating its protective effects in pathological contexts.
