Western blot - Anti-Rubicon/Baron antibody [EPR26996-20] (AB307720)

Western blot : Anti-Rubicon/Baron antibody [EPR26996-20] ab307720 staining at 1/1000 dilution, shown in green; Mouse anti alpha Tubulin (ab7291) loading control staining at 1/20,000 dilution, shown in magenta. A band was observed at 130 kDa in Wild-type A549 cell lysates with no signal observed at this size in RUBCN knockout A549 cell line. To generate this image, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3pc Milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit 800CW & Goat anti-Mouse 680RD at 1/20,000 dilution.

Supplementary information

Rubicon also known as Baron is a protein that functions mechanically to regulate autophagy and endosomal maturation. It has a molecular weight of approximately 70 kDa. You can find Rubicon expressed in various tissues but it is especially abundant in the liver spleen and pancreas. The protein acts by interacting with key autophagic and endocytic machinery including Rab7 and UVRAG which modulate vesicular trafficking processes vital for cellular homeostasis.
Biological function summary

Rubicon plays a role as part of the Beclin1-PI3K complex inhibiting autophagic activity. This protein modulates the fusion of autophagosomes with lysosomes a critical step in degrading cellular components. By preventing excessive autophagy Rubicon helps maintain cellular equilibrium balancing degradation and synthesis processes. Its involvement in endo-lysosomal trafficking is essential for the management of cellular waste and nutrient recycling.

Pathways

Rubicon has an important role in the PI3K/AKT signaling and autophagy pathways. Through its interaction with proteins like Beclin1 and Rab7 Rubicon becomes a significant modulator of autophagic flux influencing cellular growth responses and survival. The protein's regulatory function in these pathways impacts how cells respond to stress and nutrient availability linking metabolic demands with appropriate cellular responses.

Aberrant expression of Rubicon connects to cancer and neurodegenerative disorders including Alzheimer's disease. In cancer Rubicon's modulation of autophagy can influence tumor growth and resistance to apoptosis often working in conjunction with Beclin1 to impact tumor dynamics. In Alzheimer's disease the interaction of Rubicon with proteins involved in autophagy and endosomal pathways like Rab7 is associated with the accumulation of pathogenic proteins highlighting its potential role in disease pathogenesis and progression.

Target data

Inhibits PIK3C3 activity; under basal conditions negatively regulates PI3K complex II (PI3KC3-C2) function in autophagy. Negatively regulates endosome maturation and degradative endocytic trafficking and impairs autophagosome maturation process. Can sequester UVRAG from association with a class C Vps complex (possibly the HOPS complex) and negatively regulates Rab7 activation (PubMed : 20974968, PubMed : 21062745).. Involved in regulation of pathogen-specific host defense of activated macrophages. Following bacterial infection promotes NADH oxidase activity by association with CYBA thereby affecting TLR2 signaling and probably other TLR-NOX pathways. Stabilizes the CYBA : CYBB NADPH oxidase heterodimer, increases its association with TLR2 and its phagosome trafficking to induce antimicrobial burst of ROS and production of inflammatory cytokines (PubMed : 22423966). Following fungal or viral infection (implicating CLEC7A (dectin-1)-mediated myeloid cell activation or RIGI-dependent sensing of RNA viruses) negatively regulates pro-inflammatory cytokine production by association with CARD9 and sequestering it from signaling complexes (PubMed : 22423967).
