Description
Alternative Products
Event=Alternative splicing; Named isoforms=2; Name=1; IsoId=Q92843-1; Sequence=Displayed; Name=3; Synonyms=BCL2L2-PABPN1; IsoId=Q92843-2; Sequence=VSP_042064; Note=Based on a readthrough transcript which may produce a BCL2L2-PABPN1 fusion protein. No experimental confirmation available. Contains a phosphoserine at position 177.;
Domain
The BH1 and BH2 motifs form a hydrophobic groove which acts as a docking site for the BH3 domain of some pro-apoptotic proteins. The C-terminal residues of BCL2L2 fold into the BH3- binding cleft and modulate pro-survival activity by regulating ligand access. When BH3 domain-containing proteins bind, they displace the C-terminus, allowing its insertion into the membrane and neutralizing the pro-survival activity of BCL2L2.
Domain
The BH4 motif seems to be involved in the anti-apoptotic function.
Function
Promotes cell survival. Blocks dexamethasone-induced apoptosis. Mediates survival of postmitotic Sertoli cells by suppressing death-promoting activity of BAX. {ECO:0000269|PubMed:8761287}.

Sequence Caution
Sequence=BAA19666.2; Type=Erroneous initiation; Note=Translation N-terminally shortened.; Evidence={ECO:0000305};
Similarity
Belongs to the Bcl-2 family. {ECO:0000305}.
Subcellular Location
Mitochondrion membrane {ECO:0000269|PubMed:11423909, ECO:0000269|PubMed:12952938}; Peripheral membrane protein {ECO:0000269|PubMed:11423909, ECO:0000269|PubMed:12952938}. Note=Loosely associated with the mitochondrial membrane in healthy cells. During apoptosis, tightly bound to the membrane.
Subunit
Interacts with BOP. {ECO:0000250}.
Tissue Specificity
Expressed (at protein level) in a wide range of tissues with highest levels in brain, spinal cord, testis, pancreas, heart, spleen and mammary glands. Moderate levels found in thymus, ovary and small intestine. Not detected in salivary gland, muscle or liver. Also expressed in cell lines of myeloid, fibroblast and epithelial origin. Not detected in most lymphoid cell lines. {ECO:0000269|PubMed:11423909}.
