Cellular Localization

Antigen Cellular Localization: Isoform Bcl-X(L): Mitochondrion inner membrane. Mitochondrion outer membrane. Mitochondrion matrix. Cytoplasmic vesicle, secretory vesicle, synaptic vesicle membrane. Cytoplasm, cytosol. Cytoplasm, cytoskeleton, microtubule organizing center, centrosome. Nucleus membrane; Single-pass membrane protein; Cytoplasmic side. Note=After neuronal stimulation, translocates from cytosol to synaptic vesicle and mitochondrion membrane in a calmodulin-dependent manner (By similarity). Localizes to the centrosome when phosphorylated at Ser-49.

Host

Rabbit

Species Reactivity

Human, Mouse, Rat

Target

A synthetic peptide corresponding to residues between BH3 and BH3 of Human Bcl-x was used as the immunogen. This antibody should recognize Bcl-xL, Bcl-xS and Bcl-x(beta) as the immunogen sequence is common to them. The antibody does not cross-react with other Bcl-2 family members.

Clone

E18

Symbol

BCL2L, BCLX

GeneID

UniProt ID

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(S) promotes apoptosis.

Summary

Bcl-x, a member of the Bcl-2 protein family, inhibits cell death, or apoptosis (1). Bcl-x is expressed as two isomeric forms, Bcl-xL and Bcl-xS, and is typically present in the cytosol in association with the mitochondrial membrane. Bcl-xL forms heterodimers with various proteins, including Bax, Bak and Bcl-2 (2). It has been found that eterodimerization with Bax does not seem to be required for anti-apoptotic activity (3). Since Bcl-xL can form an ion channel in synthetic lipid membranes, there is a strong possibility that this property plays a role in heterodimerization-independent cell survival (4). The Bcl-X(S) isoform promotes apoptosis.

Form

50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA.

Storage & Stability

Store at +4°C short term. For long-term storage, aliquot and store at -20°C or below. Stable for 12 months at -20°C. Avoid repeated freeze-thaw cycles.

Applications

FC, IHC, WB

Dilution

FC~~1:50 IHC~~1:50~1:100 WB~~1:1000~10000
