    Abstract GRB2 is an adaptor protein of HER2 (and several other tyrosine kinases), which we identified as a novel BECN1 (Beclin 1) interacting partner. GRB2 co-immunoprecipitated with BECN1 in several breast cancer cell lines and regulates autophagy through a mechanism involving the modulation of the class III PI3Kinase VPS34 activity. In ovo studies in a CAM (Chicken Chorioallantoic Membrane) model indicated that GRB2 knockdown, as well as overexpression of GRB2 loss-of-function mutants (Y52A and S86A-R88A) compromised tumor growth. These differences in tumor growth correlated with differential autophagy activity, indicating that autophagy effects might be related to the effects on tumorigenesis. Our data highlight a novel function of GRB2 as a BECN1 binding protein and a regulator of autophagy.

    Abstract Autophagy is an intracellular degradation process that maintains the cellular homeostasis and it is regulated in multiple ways, both in health and disease. Assessment of autophagic flux in cells is an important approach for understanding the function of autophagy in biological contexts. Here, we describe a new tool for the qualitative and quantitative determination of autophagic flux using a dual lentiviral reporter system that generates a fusion HiBiT-GFP-LC3B protein suitable for generating stable cell lines.
