Beclin 2 negatively regulates innate immune signaling and tumor development.
Title: Beclin 2 negatively regulates innate immune signaling and tumor development.
Further data showed that reactive oxygen species-c-Jun activation by HBx resulted in the release of beclin-1 from its association with beclin-2 to form a complex with VPS34, thus enhancing autophagosome formation.
Title: Reactive Oxygen Species-Mediated c-Jun NH(2)-Terminal Kinase Activation Contributes to Hepatitis B Virus X Protein-Induced Autophagy via Regulation of the Beclin-1/Bcl-2 Interaction.
polar BECN2 CCD interface residues result in a metastable homodimer, facilitating dissociation, but enable better interactions with polar ATG14 residues stabilizing the BECN2:ATG14 heterodimer.
Title: BECN2 interacts with ATG14 through a metastable coiled-coil to mediate autophagy.
Both transfected and endogenous beclin 2 coimmunoprecipitated with vGPCR. Beclin 2 overexpression decreased HA-vGPCR steady-state levels. It regulates vGPCR levels by a lysosomal degradation pathway.
Title: Endolysosomal trafficking of viral G protein-coupled receptor functions in innate immunity and control of viral oncogenesis.
distinct patterns of Beclin 1 and Beclin 2 were associated with aggressive clinical outcomes. Beclin 1 overexpression, as well as Beclin 2 overexpression and depletion, contributed to tumor growth.
Title: Expression of Beclin Family Proteins Is Associated with Tumor Progression in Oral Cancer.
Study identified a previously uncharacterized mammalian-specific protein, Beclin 2, which, like Beclin 1, functions in autophagy and interacts with class III PI3K complex components.[Beclin 2]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
