Abstract

Autophagy, a cellular degradation system, promotes both cell death and survival. The interaction between Bcl-2 family proteins and Beclin 1, a Bcl-2 interacting protein that promotes autophagy, can mediate crosstalk between autophagy and apoptosis. We investigated the interaction between anti-and pro-apoptotic Bcl-2 proteins with Beclin 1. Our results show that Beclin 1 directly interacts with Bcl-2, Bcl-x(L), Bcl-w and to a lesser extent with Mcl-1. Beclin 1 does not bind the pro-apoptotic Bcl-2 proteins. The interaction between Beclin 1 and the anti-apoptotic protein Bcl-x(L) was inhibited by BH3-only proteins, but not by multi-domain proteins. Sequence alignment and structural modeling suggest that Beclin 1 contains a putative BH3-like domain which may interact with the hydrophobic grove of Bcl-x(L). Mutation of the Beclin 1 amino acids predicted to mediate this interaction inhibited the association of Beclin 1 with Bcl-x(L). Our results suggest that BH3 only proapoptotic Bcl-2 proteins may modulate the interactions between Bcl-x(L) and Beclin 1.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
