Beclin1-ATG14L interaction inhibitor 1 (com 19) is a selective Beclin1-ATG14L interaction inhibitor. This protein interaction mechanism specifically targets complex I of the lipid kinase VPS34 without affecting complex II. Because the integrity of VPS34 complex II depends on the Beclin 1-UVRAG interaction. Beclin1-ATG14L interaction inhibitor 1 can disrupt the formation of VPS34 complex I and inhibit autophagy , but does not affect complex II-related vesicle transport.
