    Flow cytometric analysis of 1X106 Jurkat cells labeling Bcl-XL Antibody (HY-P81614, red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. Then stained with the primary antibody at 1/50 dilution for an hour at 4℃. AF488-conjugated Goat Anti-Rabbit IgG H&L (HY-P8002) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Rabbit IgG Isotype Control (HY-P80879, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black).

Background

  • Function

    Bcl-xL, encoded by BCL2L1, is a major anti-apoptotic member of the BCL-2 family that regulates mitochondrial apoptosis through interactions with pro-apoptotic proteins and preservation of mitochondrial integrity[1][2]. Mechanistically, Bcl-xL suppresses mitochondrial outer membrane permeabilization, limits BAX/BAK activation, and modulates cellular bioenergetics, calcium signaling, and autophagy, linking survival pathways with metabolic adaptation under cellular stress[1][3]. Beyond canonical apoptosis control, Bcl-xL interacts with Beclin-1 and intracellular calcium regulators, including IP3 receptors and VDAC1, thereby influencing autophagy, endoplasmic reticulum-mitochondrial communication, and stress responses[1][4]. In disease models, elevated Bcl-xL expression promotes tumor cell survival, therapeutic resistance, angiogenesis, and metastatic progression across hematologic malignancies and solid tumors, including melanoma and breast cancer[1][5]. Compared with related BCL2L1 splice isoforms, Bcl-xL functions predominantly as a pro-survival protein, whereas the alternatively spliced Bcl-xS isoform exhibits pro-apoptotic activity, highlighting the biological significance of isoform-specific regulation in apoptosis research[2][6]. For experimental applications, Bcl-xL is a validated target of BH3 mimetics and other apoptosis-directed strategies, and its inhibition is widely used to investigate mitochondrial apoptotic priming, drug resistance mechanisms, and cancer cell dependency on anti-apoptotic signaling networks[1][7].

  • Expression


    Tissue_specificity:Bcl-X (S) is highly expressed in cells with a rapid cell turnover rate, such as developing lymphocytes. In contrast, Bcl-X (L) is found in tissues containing long-lived amitotic cells, such as adult brain tissue.

  • Isoforms & Post-Translational Modification

    Q07817 has 3 isomers: Q07817-1: 26049 Da (predicted); Q07817-2: 18894 Da (predicted); Q07817-3: 25290 Da (predicted).
    Proteolytically cleaved by caspases during apoptosis. The cleaved protein, lacking the BH4 motif, has pro-apoptotic activity;Phosphorylated on Ser-62 by CDK1. This phosphorylation is partial in normal mitotic cells, but complete in G2-arrested cells upon DNA-damage, thus promoting subsequent apoptosis probably by triggering caspases-mediated proteolysis. Phosphorylated by PLK3, leading to regulate the G2 checkpoint and progression to cytokinesis during mitosis. Phosphorylation at Ser-49 appears during the S phase and G2, disappears rapidly in early mitosis during prometaphase, metaphase and early anaphase, and re-appears during telophase and cytokinesis;Ubiquitinated by RNF183 during prolonged ER stress, leading to degradation by the proteosome

  • Subunit

    Homodimer. Interacts with BCL2L11 (By similarity). Interacts with BAD. Interacts with PGAM5. Interacts with HEBP2. Interacts with p53/TP53 and BBC3; interaction with BBC3 disrupts the interaction with p53/TP53. Interacts with ATP5F1A and ATP5F1B; the interactions mediate the association of isoform Bcl-X(L) with the mitochondrial membrane ATP synthase F(1)F(0) ATP synthase. Interacts with VDAC1 (PubMed:25296756). Interacts with BCL2L11 (via BH3) (PubMed:27013495). Interacts with RNF183 (PubMed:29507230). Interacts with GIMAP3/IAN4 and GIMAP5/IAN5 (PubMed:16509771). Interacts with GIMAP5 and HSPA8/HSC70; the interaction between HSPA8 and BCL2L1 is impaired in the absence of GIMAP5 (By similarity). Interacts with isoform 4 of CLU; this interaction releases and activates BAX and promotes cell death (PubMed:21567405)
