Beclin is a Bcl-2 binding protein. Its structure includes a Bcl-2 binding coiled-coil region，and a leucine-rich nuclear export signal （NES）. Beclin protein colocalizes with intracytoplasmic organelles and nuclei in normal COS7 and MCF7 cells. Beclin interaction with Bcl-2 may be involved with host viral defense，since over expression of beclin inhibits Sindbis virus replication and expression of beclin lacking the Bcl-2 binding domain has no antiviral effects.
應用類型
Western blotting （0.5-2 ug/ml）. However， the optimal concentrations should be determined individually. Other applications have not been tested. The antibody recognizes ~53 kDa beclin 1 in Jurkat cell lysate. A weak band of ~110 kDa （possibly dimer） can also be observed in Jurkat cells. In mouse intestine tissue lysate， the antibody recognizes a ~100 kDa band （possibly dimer）. Reactivity to other species has not been tested.
