BCL2L1 also known as Bcl-2-like protein 1 isoform a. This protein is a member of BCL-2 protein family. BCL2L1 is located at the outer mitochondrial membrane, and have been shown to regulate outer mitochondrial membrane channel (VDAC) opening. Also, BCL2L1 controls a switch between cell death modes during mitotic arrest. Recombinant mouse BCL2L1, fused to His-tag at N-terminus was expressed in E.coli and purified by using conventional chromatography techniques.
