The antigen is a phosphopeptide corresponding to amino acid residues surrounding the phospho-Ser234 of human beclin-1.

The antibody is prepared from pooled rabbit serum by affinity purification via sequential chromatography on phospho- and dephospho- peptide affinity columns.

Biological Significance: ExpandCollapse

Beclin-1 plays a key role in tumor suppression and autophagy. It has been suggested that autophagy proteins such as beclin-1 can inhibit tumorigenesis and that decreased expression of these proteins may contribute to the development of human malignancies (Liang et al., 1999). Beclin-1 has been shown to interact with 14-3-3 proteins through Akt-mediated phosphorylation at Ser234 (Wang et al., 2012).
