Table 1. Beclin-1 interacting proteins implicated in starvation-induced autophagy.

Protein Interaction and function Reference
Positive regulators of autophagy
VPS34 catalytic subunit of phosphatidylinositol 3-kinase complexes 11,155
VPS15 cofactor of VPS34 required for production of PtdIns(3)P 17,151
UVRAG promotes autophagy, present in late endosomes 11,21,156
ATG14 promotes autophagy, essential for localization of VPS34 to phagophore 11,21
AMBRA1 promotes autophagy, nutrient-dependent localization of Beclin-1 131,157
HMGB1 promotes autophagy, increases VPS34 activity 158
Bif-1 promotes autophagy, promotes UVRAG-containing VPS34 complexes 159
Negative regulators of autophagy
Rubicon inhibits autophagy, antagonizes UVRAG-containing VPS34 complexes 16,19
Bcl-2 inhibits autophagy, inhibits Beclin-1-containing VPS34 complexes 142
Bcl-xL inhibits autophagy, binds Beclin-1 complexes at the ER 145
IP3R inhibits autophagy, binds Beclin-1 complexes at the ER 160
