Beclin-1 is a protein that in humans is encoded by the BECN1 gene.[5][6] Beclin-1 is a mammalian ortholog of the yeast autophagy-related gene 6 (Atg6)  and BEC-1 in the C. elegans nematode.[7] This protein interacts with either BCL-2 or PI3k class III, playing a critical role in the regulation of both autophagy and cell death.

Role in disease[edit]

Beclin-1 plays an important role in tumorigenesis, and neurodegeneration, being implicated in the autophagic programmed cell death.[8] Ovarian cancer with upregulated autophagy has a less aggressive behavior and is more responsive to chemotherapy.[9]

Schizophrenia is associated with low levels of Beclin-1 in the hippocampus of the affected which causes diminished autophagy which in turn results in increased neuronal cell death.[10]

Interactions[edit]

BECN1 has been shown to interact with:

Modulators[edit]

Trehalose
Trehalose reduces p62/Beclin-1 ratio and increases autophagy in the frontal cortex of ICR mice, possibly by increasing Beclin-1.[13]
