Secondary Information

Protein Function Bcl-2-related protein A1 is an endogenous and cytokine-stimulated mediator of cytoprotection in hyperoxic acute lung injury
Biochemical Properties The C-terminus of Bcl-2 was important for other homomeric and heteromeric protein-protein interactions.three sites of homomeric interactions were identified within Bcl-2. The carboxy terminal 37 amino acids selectively homodimerized. Two additional regions of Bcl-2 (residues 1-129 and 126-200) interacted with each other, but not themselves permitting both intra- and intermolecular association.
Significance in milk antiapoptotic in function,maintenance of binucleate cells and support placental functions during bovine gestation period
Site(s) of PTM(s)

N-glycosylation, O-glycosylation,
Predicted Disorder Regions NA
DisProt Annotation
TM Helix Prediction No TM helices
Additional Comments  First thing is that Bcl-2 may exist as both heterodimers and heteromultimers. Second thing is that molecules such as Bax and A1 may serve to cap chains of Bcl-2 homodimers by interacting with dimerization domains in the extramembrane region.
