Target description

Beclin-1 (UniProt: Q14457; also known as Coiled-coil myosin-like BCL2-interacting protein, Protein GT197) is encoded by the BECN1 (also known as GT197) gene (Gene ID: 8678) in human. Beclin-1 is a peripheral membrane protein that plays a key role in autophagy. It is a component of the PI3K (PI3KC3/PI3K-III/class III phosphatidylinositol 3-kinase) complex the core of which is composed of the catalytic subunit PIK3C3, the regulatory subunit PIK3R4 and Beclin-1 associating with additional regulatory/auxiliary subunits to form alternative complex forms. It interacts with several cofactors, such as Atg14L, UVRAG, Rubicon, Ambra1, and survivin to regulate the activity of phosphatidylinositol 3-kinase. Its coiled-coil domain (aa 142-270) can form antiparallel homodimers and mediate dimerization with the coiled coil domains of ATG14 or UVRAG. Baclin-1 contains a BH3 motif (aa 108-127) that is shown to be bound to and inhibited by Bcl-2 or Bcl-xL. It also contains a C-terminal evolutionary conserved domain (ECD; aa 245-450) that has poly-Gln-binding domains and within this ECD it has a short amino acid sequence (aa 425-450) that is required for its membrane association. Beclin can undergo cleavage into Beclin-1-C (35 kDa; aa 134-450) and Beclin-1-C (37 kDa; aa 150-450). The Beclin-1-C 35 kDa localizes to mitochondria and can promote apoptosis by inducing the mitochondrial translocation of Bax and the release of proapoptotic factor. Beclin-1 is shown to undergo caspase-mediated cleavage that promotes crosstalk between apoptosis and autophagy. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
