Our Anti-Beclin1 (Ser295) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects human, mouse, and rat Beclin1 (Ser295) and is antigen affinity purified from pooled serum. It is great for use in WB.
Western blot of wild type (WT) beclin-1 expressed in HeLa cell lysate showing specific immunolabeling of beclin-1 phosphorylated at Ser295. This immunolabeling is eliminated in the beclin-1 alanine substitution mutant (S295A: Mut) expressed in HeLa cell lysate.
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). Akt-mediated phosphorylation of beclin-1 at Ser-295 has been shown to decrease autophagy and promote oncogenesis (Wang et al., 2012).
Antigen Affinity Purified from Pooled Serum
Synthetic phospho-peptide corresponding to amino acid residues surrounding Ser295 of human beclin-1, conjugated to keyhole limpet hemocyanin (KLH).
