Background Information

BCL2L1 is a member of the BCL-2 protein family. BCL2L1 is expressed as three isoforms, Bcl-X(L),Bcl-X(s) and Bcl-X(beta) , and is located at the outer mitochondrial membrane. The Bcl-X(L) isoform is a 233 amino acid protein, acting as an apoptotic inhibitor. Bcl-XL can forms heterodimers with BAX, BAK or BCL2, and the heterodimerization with BAX does not seem to be required for anti-apoptotic activity. The Bcl-X(s) isoform is a shorter variant that is 178 amino acids in length and lacks a 63 amino acid region (amino acids 126-188), acting as an apoptotic activator. Bcl-X(beta) is a 227 amino acid protein. This antibody can recognize Bcl-XL, Bcl-X(s) and Bcl-X(Beta).
