BCL2L1

Functionⁱ

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 F₁F₀ 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).1 Publication

Isoform Bcl-X(S) promotes apoptosis.

Post-translational modificationⁱ

Proteolytically cleaved by caspases during apoptosis. The cleaved protein, lacking the BH4 motif, has pro-apoptotic activity.1 Publication

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.2 Publications

Interactionⁱ

Subunit structureⁱ

Homodimer. Isoform Bcl-X(L) forms heterodimers with BAX, BAK or BCL2. Heterodimerization with BAX does not seem to be required for anti-apoptotic activity. Interacts with BCL2L11. Interacts with BAD. Interacts (isoform Bcl-X(L)) with SIVA1 (isoform 1); the interaction inhibits the anti-apoptotic activity. Interacts with BECN1 and PGAM5. Isoform Bcl-X(L) interacts with IKZF3. Interacts with HEBP2. Isoform Bcl-X(L) interacts with RTL10/BOP. Interacts with p53/TP53 and BBC3; interaction with BBC3 disrupts the interaction with p53/TP53. Isoform Bcl-X(L) interacts with DNM1L and CLTA; DNM1L and BCL2L1 isoform BCL-X(L) may form a complex in synaptic vesicles that also contains clathrin and MFF. Interacts with ATP5F1A and ATP5F1B; the interactions mediate the association of isoform Bcl-X(L) with the mitochondrial membrane ATP synthase F₁F₀ ATP synthase. Interacts with VDAC1 (PubMed:25296756). Isoform Bcl-X(L) interacts (via the loop between motifs BH4 and BH3) with NLRP1 (via LRR repeats), but not with NLRP2, NLRP3, NLRP4, PYCARD, nor MEFV (PubMed:17418785). Interacts with BCL2L11 (via BH3) (PubMed:27013495).14 Publications
